Toyota Dynamic Force Engine
The Dynamic Force engines are a family of petrol engine series developed by Toyota under the brand's New Global Architecture (TNGA) strategy. The engines were developed alongside the TNGA family of vehicle platforms, as part of a company-wide effort to simplify the vehicles being produced by Toyota. The engine is used in various Toyota and Lexus models starting with the four-cylinder ''A25A'' type installed in XV70 series Camry in June 2017. __TOC__ Overview The engine was developed as an engine that is claimed to achieve both driving performance and environmental performance while pursuing high efficiency and low fuel consumption as well as having a "direct feeling, smooth and pleasant acceleration performance". Specifically, the cylinder head and intake port design improves the tumble flow (longitudinal vortex) to increase the air intake volume–the majority of intake flow is across that portion of the valve closest to cylinder centreline. Other methods include: * Expa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Straight-four Engine
A straight-four engine (also called an inline-four) is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The vast majority of automotive four-cylinder engines use a straight-four layout (with the exceptions of the flat-four engines produced by Subaru and Porsche) and the layout is also very common in motorcycles and other machinery. Therefore the term "four-cylinder engine" is usually synonymous with straight-four engines. When a straight-four engine is installed at an inclined angle (instead of with the cylinders oriented vertically), it is sometimes called a slant-four. Between 2005 and 2008, the proportion of new vehicles sold in the United States with four-cylinder engines rose from 30% to 47%. By the 2020 model year, the share for light-duty vehicles had risen to 59%. Design A four-stroke straight-four engine always has a cylinder on its power stroke, unlike engines with fewer cylinders where there is no power stroke occu ...

Gasoline Direct Injection
Gasoline direct injection (GDI), also known as petrol direct injection (PDI), is a mixture formation system for internal combustion engines that run on gasoline (petrol), where fuel is injected into the combustion chamber. This is distinct from manifold fuel injection systems, which inject fuel into the intake manifold. The use of GDI can help increase engine efficiency and specific power output as well as reduce exhaust emissions. The first GDI engine to reach production was introduced in 1925 for a low-compression truck engine. Several German cars used a Bosch mechanical GDI system in the 1950s, however usage of the technology remained rare until an electronic GDI system was introduced in 1996 by Mitsubishi for mass-produced cars. GDI has seen rapid adoption by the automotive industry in recent years, increasing in the United States from 2.3% of production for model year 2008 vehicles to approximately 50% for model year 2016.

Hydraulic Tappet
A hydraulic tappet, also known as a hydraulic valve lifter or hydraulic lash adjuster, is a device for maintaining zero valve clearance in an internal combustion engine. Conventional solid valve lifters require regular adjusting to maintain a small clearance between the valve and its rocker or cam follower. This space prevents the parts from binding as they expand with the engine's heat, but can also lead to noisy operation and increased wear as the parts rattle against one another until they reach operating temperature. The hydraulic lifter was designed to compensate for this small tolerance, allowing the valve train to operate with zero clearance—leading to quieter operation, longer engine life, and eliminating the need for periodic adjustment of valve clearance. The hydraulic lifter, situated between the camshaft and each engine's valve, is a hollow steel cylinder encasing an internal piston. This piston is held at the outer limit of its travel with a strong spring. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VVT-i
VVT-i, or Variable Valve Timing with intelligence, is an automobile variable valve timing technology developed by Toyota. It was first introduced in 1995 with the '' 2JZ-GE'' engine found in the JZS155 Toyota Crown and Crown Majesta. The VVT-i system replaces the Toyota VVT system first introduced in 1991 with the five-valve per cylinder '' 4A-GE'' engine found in the AE101 Corolla Levin and Sprinter Trueno. The VVT system is a 2-stage hydraulically controlled cam phasing system. VVT-i varies the timing of the intake valves by adjusting the relationship between the camshaft drive (belt or chain) and intake camshaft. Engine oil pressure is applied to an actuator to adjust the camshaft position. Adjustments in the overlap time between the exhaust valve closing and intake valve opening result in improved engine efficiency. Variants of the system, including VVTL-i, Dual VVT-i, VVT-iE, VVT-iW and Valvematic, have followed. VVTL-i VVTL-i (Variable Valve Timing and Lift intell ...

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 t ...

Toyota M Engine
Toyota Motor Corporation's M family of engines were a longitudinally mounted straight-6 engine design. They were used from the 1960s through the 1990s. All M family engines were OHC designs. While the M family was born with a chain-driven single camshaft it evolved into a belt drive DOHC system after 1980. All M family engines used a cast-iron block with an aluminum cylinder head, and were built at the Toyota Kamigo plant in Toyota City, Japan. The M-E variant, available only in the Japanese domestic market, was the first Toyota engine to be equipped with fuel injection (at the same time as the 4-cylinder 18R-E). The 4M-E was the first Toyota engine to be equipped with fuel injection for non-Japanese markets. The M family were Toyota's most prestigious engines (apart from the uncommon '' V family'' V8) for 30 years. They were commonly found on the large Toyota Crown, Mark II, and Supra models. M The first M was a version produced from 1965 through 1988. It was a 2- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
