Nissan NAPS
NAPS stands for Nissan Anti Pollution System a moniker used in Japan to identify vehicles built with emission control technology. The technology was installed so that their vehicles would be in compliance with Japanese Government emission regulations passed in 1968. The term was first introduced in Japan, with an externally mounted badge on the trunk of vehicles equipped. Nissan's implementation began with the Y44E V8 engine installed in the Nissan President along with all vehicles installed with the Nissan L engine and the Nissan A engine in 1975. The initial introduction of Nissan's technology was the installation of an exhaust gas recirculation valve, followed with the addition of a catalytic converter and an air pump that added oxygen into the exhaust to promote higher temperatures in the catalytic converter, thus cleaning the exhaust further. The NAPS-Z technology, introduced in 1978, was developed with assistance from Hitachi.Yamaguchi, Jack K., "Japan: Reluctant Number One" ...

Emission Standard
Emission standards are the legal requirements governing air pollutants released into the atmosphere. Emission standards set quantitative limits on the permissible amount of specific air pollutants that may be released from specific sources over specific timeframes. They are generally designed to achieve air quality standards and to protect human life. Different regions and countries have different standards for vehicle emissions. Regulated sources Many emissions standards focus on regulating pollutants released by automobiles (motor cars) and other powered vehicles. Others regulate emissions from industry, power plants, small equipment such as lawn mowers and diesel generators, and other sources of air pollution. The first automobile emissions standards were enacted in 1963 in the United States, mainly as a response to Los Angeles' smog problems. Three years later Japan enacted their first emissions rules, followed between 1970 and 1972 by Canada, Australia, and several Eu ...

Nissan A Engine
The Nissan A series of internal combustion gasoline engines have been used in Datsun, Nissan and Premier brand vehicles. Displacements of this four-stroke engine family ranged from 1.0-liter to 1.5-liter and have been produced from 1967 till 2009. It is a small-displacement four-cylinder straight engine. It uses a lightweight cast iron block and an aluminum cylinder head, with overhead valves actuated by pushrods. The Nissan A engine design is a refined, quiet and durable gasoline engine. It appears to be a modern replacement of the earlier iron-headed Nissan C and Nissan E engines and is of similar dimensions. The 1960s E series was an all-new design from newly acquired Aichi Kokuki, and integrated Nissan's improvements to the BMC B-Series engine design of the 1950s (Nissan was a licensee of Austin Motor Company technology), mainly comprising changing the camshaft from the left side to the right side so removing the intrusion of the pushrods from the porting allowing 8 ind ...

Exhaust Gas Recirculation
In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide () emissions reduction technique used in petrol/gasoline, diesel engines and some hydrogen engines. EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders. The exhaust gas displaces atmospheric air and reduces in the combustion chamber. Reducing the amount of oxygen reduces the amount of fuel that can burn in the cylinder thereby reducing peak in-cylinder temperatures. The actual amount of recirculated exhaust gas varies with the engine operating parameters. In the combustion cylinder, is produced by high-temperature mixtures of atmospheric nitrogen and oxygen, and this usually occurs at cylinder peak pressure. In a spark-ignition engine, an ancillary benefit of recirculating exhaust gases via an external EGR valve is an increase in efficiency, as charge dilution allows a larger throttle position and reduces associated pumping losses.

Catalytic Converter
A catalytic converter is an exhaust emission control device that converts toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction. Catalytic converters are usually used with internal combustion engines fueled by gasoline or diesel, including lean-burn engines, and sometimes on kerosene heaters and stoves. The first widespread introduction of catalytic converters was in the United States automobile market. To comply with the U.S. Environmental Protection Agency's stricter regulation of exhaust emissions, most gasoline-powered vehicles starting with the 1975 model year are equipped with catalytic converters. These "two-way" converters combine oxygen with carbon monoxide (CO) and unburned hydrocarbons (HC) to produce carbon dioxide (CO2) and water (H2O). Although two-way converters on gasoline engines were rendered obsolete in 1981 by "three-way" converters that also reduce oxides of nitrogen (); they ...

Dual Ignition
Dual Ignition is a system for spark-ignition engines, whereby critical ignition components, such as spark plugs and magnetos, are duplicated. Dual ignition is most commonly employed on aero engines,Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 177. Aviation Supplies & Academics, 1997. Aviation Publishers Co. Limited, ''From the Ground Up'', (27th revised edition), page 67, and is sometimes found on cars and motorcycles. Dual ignition provides two advantages: redundancy in the event of in-flight failure of one ignition system; and more efficient burning of the fuel-air mixture within the combustion chamber. In aircraft and gasoline-powered fire fighting equipment, redundancy is the prime consideration, but in other vehicles the main targets are efficient combustion and meeting emission law requirements. Efficiency A dual ignition system will typically provide that each cylinder has twin spark plugs, and that the engine will have at least two ignition ...

Nissan Z Engine
The Nissan Z engine is a series of automobile and light truck four-cylinder engines that was engineered by Nissan Machinery, manufactured by the Nissan Motor Company from 1979 through August 1989. All Z engines had 4 cylinders, a total of 8 valves and a single overhead camshaft (SOHC). Displacements ranged from 1.6 L to 2.4 L.The Z series' engine blocks were nearly identical to those of the earlier L Series with the exception of the Z24. While the Z16 and Z18 engines had a deck height similar to the earlier L13/L14/L16/L18 variants, the Z24 had a taller deck height to accommodate a longer stroke. The most notable difference between the Z-series engine and its predecessor was the introduction of a new crossflow cylinder head which reduced emissions by moving the intake ports to the right side of the engine opposite the exhaust ports. This change allows the exhaust port velocity to more effectively scavenge the cylinder and reduce reversion pulses to enhance induction. This ...
