Turbo Diesel
The term turbo-diesel, also written as turbodiesel and turbo diesel, refers to any diesel engine equipped with a turbocharger. As with other engine types, turbocharging a diesel engine can significantly increase its efficiency and power output, especially when used in combination with an intercooler. Turbocharging of diesel engines began in the 1920s with large marine and stationary engines. Trucks became available with turbo-diesel engines in the mid-1950s, followed by passenger cars in the late 1970s. Since the 1990s, the compression ratio of turbo-diesel engines has been dropping. Principle Diesel engines are typically well suited to turbocharging due to two factors: * A "lean" air–fuel ratio, caused when the turbocharger supplies excess air into the engine, is not a problem for diesel engines, because the torque control is dependent on the mass of fuel that is injected into the combustion chamber (i.e. air-fuel ratio), rather than the quantity of the air-fuel mixture. ...

Land Rover Engines
Engines used by the British company Land Rover in its 4×4 vehicles have included four-cylinder petrol engines, and four- and five-cylinder diesel engines. Straight-six cylinder engines have been used for Land Rover vehicles built under licence. Land Rover has also used various four-cylinder, V8, and V6 engines developed by other companies, but this article deals only with engines developed specifically for Land Rover vehicles. Initially, the engines used were modified versions of standard Rover car petrol engines, but the need for dedicated in-house units was quickly realised. The first engine in the series was the 1.6-litre petrol of 1957, and this design was improved, expanded, and modified over several versions, culminating in the 300Tdi of 1994, which ceased production in 2006. Over 1.2 million engines in the series have been built. From 1998, the Td5 engine was fitted to Land Rover products. Whilst this five-cylinder turbodiesel was unrelated in any way to the four-cyli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Noise, Vibration, And Harshness
Noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks. While noise and vibration can be readily measured, harshness is a subjective quality, and is measured either via jury evaluations, or with analytical tools that can provide results reflecting human subjective impressions. The latter tools belong to the field psychoacoustics. Interior NVH deals with noise and vibration experienced by the occupants of the cabin, while exterior NVH is largely concerned with the noise radiated by the vehicle, and includes drive-by noise testing. NVH is mostly engineering, but often objective measurements fail to predict or correlate well with the subjective impression on human observers. For example, although the ear's response at moderate noise levels is approximated by A-weighting, two different noises with the same A-weighted level are not necessarily eq ...

Euro 6
The European emission standards are vehicle emission standards for pollution from the use of new land surface vehicles sold in the European Union and EEA member states and the UK, and ships in EU waters. The standards are defined in a series of European Union directives staging the progressive introduction of increasingly stringent standards. , the standards do not include non-exhaust emissions such as particulates from tyres and brakes. Details of Euro 7 have been postponed to 12 October 2022. Background In the European Union, emissions of nitrogen oxides (), total hydrocarbon (THC), non-methane hydrocarbons (NMHC), carbon monoxide (CO) and particulate matter (PM) are regulated for most vehicle types, including cars, trucks (lorries), locomotives, tractors and similar machinery, barges, but excluding seagoing ships and aeroplanes. For each vehicle type, different standards apply. Compliance is determined by running the engine at a standardised test cycle. Non-compl ...

Common Rail
Common rail direct fuel injection is a direct fuel injection system built around a high-pressure (over ) fuel rail feeding solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles). High-pressure injection delivers power and fuel consumption benefits over earlier lower pressure fuel injection, by injecting fuel as a larger number of smaller droplets, giving a much higher ratio of surface area to volume. This provides improved vaporization from the surface of the fuel droplets, and so more efficient combining of atmospheric oxygen with vaporized fuel delivering more complete combustion. Common rail injection is widely used in diesel engines. It is also the basis of gasoline direct injection systems used on petrol engines. History Vickers pioneered the use of common rail injection in submarine engines. Vickers engines with the common rail fuel system were first used in 1916 in the G-class submarines. It used four plunger pumps to deliver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indirect Injection
Indirect injection in an internal combustion engine is fuel injection where fuel is not directly injected into the combustion chamber. Gasoline engines equipped with indirect injection systems, wherein a fuel injector delivers the fuel at some point before the intake valve, have mostly fallen out of favor to direct injection. However, certain manufacturers such as Volkswagen, Toyota and Ford have developed a 'dual injection' system, combining direct injectors with port (indirect) injectors, combining the benefits of both types of fuel injection. Direct injection allows the fuel to be precisely metered into the combustion chamber under high pressure which can lead to greater power, fuel efficiency. The issue with direct injection is that it typically leads to greater amounts of particulate matter and with the fuel no longer contacting the intake valves, carbon can accumulate on the intake valves over time. Adding indirect injection keeps fuel spraying on the intake valves, reducin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compression Ratio
The compression ratio is the ratio between the volume of the cylinder and combustion chamber in an internal combustion engine at their maximum and minimum values. A fundamental specification for such engines, it is measured two ways: the static compression ratio, calculated based on the relative volumes of the combustion chamber and the cylinder when the piston is at the bottom of its stroke, and the volume of the combustion chamber when the piston is at the top of its stroke. The dynamic compression ratio is a more advanced calculation which also takes into account gasses entering and exiting the cylinder during the compression phase. Effect and typical ratios A high compression ratio is desirable because it allows an engine to extract more mechanical energy from a given mass of air–fuel mixture due to its higher thermal efficiency. This occurs because internal combustion engines are heat engines, and higher compression ratios permit the same combustion temperature ...

Peugeot 604
The Peugeot 604 is an executive car produced by the French manufacturer Peugeot from 1975 to 1985. 153,252 cars were sold during its 10-year production life. It was made in France and also assembled by Kia in South Korea. The Pininfarina-designed 604 was unveiled at the Geneva Motor Show in March 1975 and drew praise for its formal, handsome styling. Denmark's ''Bilrevyen 1976'' ("The Car Review 1976"), for example, described the styling as possessing a "calm elegance". Sales began in September 1975. Based "on the principles of the Peugeot 504",''Autocar'', November 1977, p. 17 using its bulkhead, doors, and part of the 504 floorpan, and usually powered by the then-new 2.7-litre V6 PRV engine, developed in conjunction with Renault and Volvo, the car was Peugeot's first entry into the large luxury saloon market for 40 years - the most recent being the short-lived Peugeot 601 of 1934.

Mercedes-Benz OM617 Engine
The OM617 engine family is a straight-5 diesel automobile engine from Mercedes-Benz used in the 1970s and 1980s. It is a direct development from the straight-4 OM616. It was sold in vehicles from 1974 to 1991. The OM617 is considered to be one of the most reliable engines ever produced with engines often reaching over without being rebuilt and is one of the key reasons for Mercedes' popularity in North America in the 1980s, as it was powerful and reliable compared to other automotive diesels of the time. It is also a very popular choice for the use of alternative fuels, mainly straight or waste vegetable oil and biodiesel, although the use of these fuels may cause engine damage over time if not processed properly before use. OM617 Naturally Aspirated Essentially an OM616 with an extra cylinder, it debuted in 1974 with the W115(240 3.0d) chassis. Bore and stroke was . It was originally .

Mercedes-Benz W116
The Mercedes-Benz W116 is a series of flagship luxury sedans produced from September 1972 until 1980. The W116 automobiles were the first Mercedes-Benz models to be officially called S-Class, although earlier sedan models had already unofficially been designated with the letter 'S' – for ''Sonderklasse'' or "special class." The ''W116'' was selected European Car of the Year in 1974. History The 'new' S-class generation development began in 1966, which was only a year after the launch of the W108/09. This was the first Mercedes saloon to feature the brand new corporate styling theme which was to be continued until 1993 when the 190 was discontinued. The design, finalized in December 1969 was a dramatic leap forward, with more masculine lines that combined to create an elegant and sporty character. The basic design concept carried through the themes originally introduced on the R107 SL-Class roadster, especially the front and rear lights. As for the SL, the W116 received the ri ...

Mercedes-Benz C111
The Mercedes-Benz C111 was a series of experimental automobiles produced by Mercedes-Benz in the 1960s and 1970s. The company was experimenting with new engine technologies, including Wankel engines, diesel engines, and turbochargers, and used the basic C111 platform as a testbed. Other experimental features included multi-link rear suspension, gull-wing doors and a luxurious interior with leather trim and air conditioning. History The first version of the C111 was completed in 1969. The car used a fiberglass body shell and with a mid-mounted three-rotor direct fuel injected Wankel engine (code named M950F). The next C111 appeared in 1970. It used a four-rotor engine producing 257 kW (350 hp). The car reportedly could reach a speed of . The company decided not to adopt the Wankel engine and turned to diesel experiments for the second and third C111s. The C111-IID produced and was based on the 240D W115 model OM616 engine. The C111-III was powered by a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
