VTEC is a system developed by Honda to improve the volumetric efficiency of a four-stroke internal combustion engine, resulting in higher performance at high RPM, and lower fuel consumption at low RPM. The VTEC system uses two camshaft profiles and hydraulically selects between profiles. It was invented by Honda engineer Ikuo Kajitani. It is distinctly different from standard VVT systems which change only the valve timings and do not change the camshaft profile or valve lift in any way.
Nissan Ecology Oriented Variable Valve Lift and Timing is an automobile variable valve timing technology developed by Nissan. VVL varies the duration, and lift of valves by using hydraulic pressure switch between two different sets of camshaft lobes. VVT varies the valve timing throughout the RPM range. Together they function similarly to Honda's VTEC system.
The Toyota A Series engines are a family of inline-four internal combustion engines with displacement from 1.3 L to 1.8 L produced by Toyota Motor Corporation. The series has cast iron engine blocks and aluminum cylinder heads. To make the engine as short as possible, the cylinders are siamesed.
The High Value engine family from General Motors is a group of cam-in-block or overhead valve V6 engines. These engines feature cast iron blocks and aluminum heads, and use the same 60° vee bank as the 60° V6 family they are based on, but the new 99 mm (3.90 in) bore required offsetting the bores by 1.5 mm (0.059 in) away from the engine center line. These engines are the first cam-in-block engines to implement variable valve timing, and won the 2006 Breakthrough Award from Popular Mechanics for this innovation. For the 2007 model year, the 3900 engine featured optional displacement on demand or "Active Fuel Management" which deactivates a bank of cylinders under light load to increase highway fuel economy. It was rumored that GM would produce a 3-valve design, but that never came to be. These engines were produced primarily at the GM factory in Tonawanda, New York, and at the Ramos Arizpe engine plant in Mexico. The assembly line for this engine was manufactured by Hirata Corporation at its powertrain facility in Kumamoto, Japan.
The VK engine is a V8 piston engine from Nissan. It is an aluminum DOHC 4-valve design.
The VQ is a family of V6 automobile petrol engines developed by Nissan and produced in displacements varying from 2.0 L to 4.0 L. Designed to replace the VG series, the all-aluminium 4-valve per cylinder DOHC design debuted with Nissan's EGI/ECCS sequential multi-point fuel injection (MPFI) system. Changes from the VG engine include switching to a timing chain from a timing belt, and relocating the water pump from the outside of the engine to inside the timing cover where the pump is driven by the timing chain. Later versions featured various improvements, such as variable valve timing, and NEO-Di designated VQ engines replace MPFI with direct fuel injection.
The RB engine is an oversquare 2.0–3.0 L straight-6 four-stroke gasoline engine from Nissan, originally produced from 1985 to 2004. The RB followed the 1983 VG-series V6 engines to offer a full, modern range in both straight or V layouts.
The VG engine is a family of V6 engines designed and produced by Nissan between 1983 and 2004.
The QG engine is a 1.3 L (1,295 cc), 1.5 L (1,497 cc), 1.6 L (1,597 cc) and 1.8 L (1,769 cc) straight-4 piston engine from Nissan. It is a lean-burn aluminum DOHC 4-valve design with variable valve timing and optional NEO Di direct injection.
The SR engine is a series of 1.6 L (1,596 cc), 1.8 L (1,838 cc) or 2.0 L (1,998 cc) straight-four, four-stroke gasoline engines manufactured by Nissan. It has an aluminium head and block with steel sleeves and has a DOHC 4-valve design, with variable valve timing on select models.
The KA engines were a series of four-stroke inline-four gasoline piston engines manufactured by Nissan, which were offered in 2.0 and 2.4 L. The engines blocks were made of cast-iron, while the cylinder heads were made of aluminum.
The GA engine is a 1.3 to 1.6 L inline-four piston engine from Nissan. It has a cast-iron block and an aluminum head. There are SOHC and DOHC versions, 8, 12, and 16 valve versions, carbureted, single-point, and multi-point injected versions, and versions with variable valve timing (GA16DE). The GA was produced from August 1987 through 2013. Since 1998, it was only available from Mexico in the B13.
The Nissan Sentra is a series of automobiles manufactured by the Japanese automaker Nissan since 1982. Since 1999, the Sentra has been categorized as a compact car, while previously it occupied the subcompact class. Until 2006, Sentra was a rebadged export version of the Japanese Nissan Sunny, but since the 2013 model year, Sentra is a rebadged export version of the Sylphy. The Sentra nameplate is not used in Japan. Many other countries in Latin America sell their versions of the Sunny as the Sentra. In Mexico, the first three generations of the Sentra were known as the Nissan Tsuru, and the B13 model was sold under that name until 2017, alongside the updated models badged as Sentra.
The CA engine is a series of 1.6 to 2.0 L Inline-4 piston engines from Nissan. It is designed for a wide variety of smaller Nissan vehicles to replace the Z engine and some smaller, four-cylinder L series engines. The "CA" stands for Clean Air, due to the installation of Nissan emission reducing technology, called NAPS-X.
The Nissan Pulsar is a line of automobiles produced by the Japanese automaker Nissan from 1978 until 2000, when it was replaced by the Nissan Bluebird Sylphy in the Japanese market.
The Nissan E series name was used on two types of automobile engines. The first was an OHV line used in the late 1950s and throughout the 1960s. The second was an OHC version ranging from 1.0 to 1.6 litres and was produced from 1981 till 1988. It was replaced by the GA engine series.
The Nissan L series of automobile engines was produced from 1966 through 1986 in both inline-four and inline-six configurations ranging from 1.3 L to 2.8 L. It is a two-valves per cylinder SOHC non-crossflow engine, with an iron block and an aluminium head. It was the engine of the Datsun 510, Datsun 240Z sports car, and the Nissan Maxima. These engines are known for their reliability, durability, and parts interchangeability.
The Nissan S20 engine 2.0 L (1,989 cc) was a straight-6 four-valve DOHC internal combustion engine produced by Nissan from 1969 to 1973, originally designed by engineers of the former Prince. It was the first mass-produced Japanese engine with more than two valves per cylinder.
The Infiniti G Line is a series of compact executive cars manufactured and marketed by Infiniti, a luxury division of Nissan, for the 1991–1996 and 1999–2016 model years — across four generations.
The Nissan Primera is a large family car which was produced by the Japanese automaker Nissan from 1990 to 2007, for the markets in Japan and Europe. In Japan, it replaced the Auster/Stanza, and was exclusive to Nissan Prince Store locations. In North America, it was the entry level luxury sports sedan for the Infiniti brand. The word "primera" in Spanish means "first", in its female form.
