Chronology | |
Predecessor | Nissan VEJ30 engine |
The Nissan VRH engine family consists of several racing engines built by Nissan Motor Company beginning in the late 1980s. All VRH engines are in a V8 configuration, with either natural aspiration or forced induction. Some VRH engines are loosely based on Nissan's production V8 engine blocks, including the VH and VK engines, while others were designed from the ground up for racing and share no components with production blocks.
The name "VRH" comes from the engines' V configuration ("V"), their purpose as racing engines ("R"), and the fact that all of them have eight cylinders (with "H" being the eighth letter of the Latin alphabet).[ citation needed ]
In 1987, Nissan began work on an engine exclusively for race use; the result was the VEJ30 engine, developed by Yoshikazu Ishikawa. This engine was based on old technology, and was not a success. For 1988, the VEJ30 was improved by Yoshimasa Hayashi and renamed the VRH30. Changes included increasing the displacement to 3.4 L (3,396 cc).
This engine was, however, still based on the obsolete VEJ30, and development of the all-new VRH35 [1] was started in parallel with the VRH30. In 1989, the VRH35 appeared as a new development engine and was used in the Nissan R89C.
A 3.0-litre variant of the VRH35Z was also used in the 1998 Courage-Nissan C51 at the 1998 24 Hours of Le Mans. Both C51s failed to finish. [2]
The design of the engine was later sold to McLaren, where it served as the basis of their M838T and M840T engines (which were used in all of McLaren's line-up since the McLaren MP4-12C). [3] [4]
The VRH30T was used in the R88C.
The VRH35Z first appeared in 1990 in the R90C.
Displacement: 3.5 L (3,495 cc)
In 1997, Nissan, working in partnership with Tom Walkinshaw Racing, fielded a VRH35L in the R390 GT1.
It has been suggested that Caparo T1 engine be merged into this article. (Discuss) Proposed since February 2024. |
The VRH35ADE was used by Infiniti in their Indy race car. [5] [6]
The VRH40ADE was used by Infiniti in their Indy race car. [7]
The VRH34A is one of two engines used in Nissan's GT500-spec GT-R.
The VRH50A was used in the Nissan R391.
The VRH34A and VRH34B are naturally aspirated engines used by Nissan in their GT-R Super GT race car from 2010.
The VRH34A is 3.4 L (3,396 cc) and produces 450–500 PS (331–368 kW; 444–493 bhp) and over 290 lb⋅ft (393 N⋅m) of torque.
The VRH34B is 3.4 L (3,396 cc) and produces 500–530 PS (368–390 kW; 493–523 bhp) and over 325 lb⋅ft (441 N⋅m) of torque.
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 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 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 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 Mitsubishi Sirius or 4G6/4D6 engine is the name of one of Mitsubishi Motors' four series of inline-four automobile engines, along with Astron, Orion, and Saturn.
The Mitsubishi 4G9 engine is a series of straight-4 automobile engines produced by Mitsubishi Motors. All are 16-valve, and use both single- and double- overhead camshaft heads. Some feature MIVEC variable valve timing, and it was the first modern gasoline direct injection engine upon its introduction in August 1996.
The J-series is Honda's fourth production V6 engine family introduced in 1996, after the C-series, which consisted of three dissimilar versions. The J-series engine was designed in the United States by Honda engineers. It is built at Honda's Anna, Ohio, and Lincoln, Alabama, engine plants.
The Honda D series inline-four cylinder engine is used in a variety of compact models, most commonly the Honda Civic, CRX, Logo, Stream, and first-generation Integra. Engine displacement ranges between 1.2 and 1.7 liters. The D Series engine is either SOHC or DOHC, and might include VTEC variable valve lift. Power ranges from 66 PS (49 kW) in the Logo to 130 PS (96 kW) in the Civic Si. D-series production commenced in 1984 and ended in 2005. D-series engine technology culminated with production of the D15B 3-stage VTEC (D15Z7) which was available in markets outside of the United States. Earlier versions of this engine also used a single port fuel injection system Honda called PGM-CARB, signifying the carburetor was computer controlled.
The Suzuki G engine is a series of three- and four-cylinder internal combustion engines manufactured by Suzuki Motor Corporation for various automobiles, primarily based on the GM M platform, as well as many small trucks such as the Suzuki Samurai and Suzuki Vitara and their derivatives.
The Honda F-Series engine was considered Honda's "big block" SOHC inline four, though lower production DOHC versions of the F-series were built. It features a solid iron or aluminum open deck cast iron sleeved block and aluminum/magnesium cylinder head.
The Honda R engine is an inline-four engine launched in 2006 for the Honda Civic (non-Si). It is fuel injected, has an aluminum-alloy cylinder block and cylinder head, is a SOHC 16-valve design and utilizes Honda's i-VTEC system. The R series engine has a compression ratio of 10.5:1, features a "drive by wire" throttle system which is computer controlled to reduce pumping losses and create a smooth torque curve.
The Subaru EJ engine is a series of four-stroke automotive engines manufactured by Subaru. They were introduced in 1989, intended to succeed the previous Subaru EA engine. The EJ series was the mainstay of Subaru's engine line, with all engines of this series being 16-valve horizontal flat-fours, with configurations available for single, or double-overhead camshaft arrangements. Naturally aspirated and turbocharged versions are available, ranging from 96 to 310 hp. These engines are commonly used in light aircraft, kit cars and engine swaps into air-cooled Volkswagens, and are also popular as a swap into copy wasserboxer engined Volkswagen T3/Vanagon. Primary engineering on the EJ series was done by Masayuki Kodama, Takemasa Yamada and Shuji Sawafuji of Fuji Heavy Industries, Subaru's parent company.
The Suzuki M engine family is a line of automobile engines from Suzuki. Ranging in displacement from 1.3 L to 1.8 L, it is a modern engine line with dual overhead cams, 16 valves, and multi-point fuel injection (MPFI).
The Isuzu 6H is a family of inline-6 cylinder Diesel engine installed in Isuzu medium duty trucks, and also installed in GM medium-duty trucks as the Duramax LG4. It is mated to the Allison 2500, 3000 and 3500 Series transmissions.
The VRT35 is 3.5L V12 piston engine from Nissan. It was developed for competition racing during the early 1990s by Nissan's motorsport division Nismo.
The Suzuki K engine family is a series of automobile engines from Suzuki, introduced in 1994. Displacements range from 0.7 L to 1.5 L. All engines have aluminium cylinder blocks with three or four cylinders in-line. Cylinder heads have two overhead camshafts, driven by chain, and four valves per cylinder. Fuel is gasoline/petrol, metered by multipoint fuel injection or direct injection. Some variants are turbocharged.
