Nissan L engine - Wikipedia, the free encyclopedia Стр. 1 Nissan L engine From Wikipedia, the free encyclopedia The Nissan L series of automobile engines ranged from 1.3 L to 2.8 L in both straight-4 and straight-6 configurations and were produced from 1967 through 1986. This was the engine of the Datsun 240Z sports car as well as the Datsun 510 and the first Nissan Maxima. These engines are known for their reliability, durability, and parts interchangeability. It is a 2-valve per cylinder SOHC non-crossflow engine, with an iron block and an aluminium head. The four cylinder L series engines were replaced with the Z series and later the CA series, while the six cylinder L series engines were replaced with the VG series and RB series. The design is often incorrectly attributed to Mercedes-Benz. In 1966 Prince Motor Company merged with Nissan. At the time of the merger, Prince was licensed to produce copies of the four and six-cylinder engines. Prince Motor Company later refined the design such that it no longer needed licensing. The engine still resembles a Mercedes in many ways, particularly the valve train.

It produces 96 hp (72 kW) through 1971 then 92 hp (69 kW). The L16 replaced the Prince G-16. Applications: Nissan Bluebird (510) Nissan 160B sedan Datsun 521 pick-up (1970–1972) Datsun 620 pick-up (1972–1974) Datsun Stanza (A10) (Australian and United Kingdom markets) (1973–1981) When this engine was installed in a 1972 Canadian 510 sedan model with gearbox (manual transmission), 2 sets of points were installed in the distributor and this second set of points was in circuit only in 3rd gear to obtain a different dwell angle. A similar arrangement exists in the US-spec 510/610 cars and 521/620 pickup trucks for the years 1970-73 L16S The L16S was an engine that was used in the 910 bluebird Sedan. This engine was equipped with an electronically controlled carburetor. Applications: Nissan Bluebird (910) L16T The L16T was basically the same as the L16 but had twin SU carbs, flat top pistons (same as ones used in 240Z) and a slightly different head. It produces 109 hp (81 kW). Applications: Nissan Bluebird (510) - At least in European version, where it was known as Datsun 1600SSS (P(L)510), 68-72. Note the L in PL was for left hand drive models. L16P The L16P is the LPG version of the L16. Applications: Nissan Bluebird (510) Nissan Violet (710) L18 The L18 was a 1770cc engine produced from 1972 through 1976. It produces 105 hp (78 kW)@5000 RPM. The L18 replaced the Prince G-18 in 1975.

It was fitted to 610 Bluebird 180B SSS, 910-U Bluebird 1.8GL "Hardtop" coupé for the UK market. It produces 110 hp (82 kW). Also Bluebird SSS Hardtop Coupe for General LH Market. ( Chassis 910 ) L18P The L18P is the LPG version of the L18 engine. Applications: Datsun Bluebird 810 Datsun Bluebird 710 L20B The L20B was a 1,952 cc (85.0 x 86.0 mm) engine produced from 1975 through 1985. It produces 97 hp (72 kW) in 1977-78 form with 102 lb·ft (138 N·m) of torque as installed in the 200SX. [1] The L20B engine utilized larger diameter (60mm) main bearings than its earlier L-series 4-cylinder predecessors. The engine used a carburetor but switched to fuel injection (and round instead of square exhaust ports) in some non-USA markets in 1977. Carburetors were used in all trucks until the L20B was replaced with the Nissan Z engine series. There were six versions of the L20B in the US- U60,U67,U95 used in cars, and U60,U67,B98,04W, and 05W used in trucks. In the US, carburetors were used on all gasoline pick-ups until fuel injection became available as an option in the 1985 720ST, and injection became standard equipment with the introduction of the 1987.5 D21 Hardbody pickups. To avoid confusion with the six-cylinder L20, Nissan called this engine the L20B and redesignated their six-cylinder engine L20A. Applications: Datsun 610 Datsun 710 Datsun 200B Datsun 620 (1976–1979, 110 hp) Datsun 200SX Datsun 510 Datsun 720 (1980) L22 This engine was used in all US-spec. gasoline-powered pick-ups in 1981, 1982 and early 1983, utilizing a Z22 crankshaft and larger-bore block and cross-flow head, giving approximately 2.2L of displacement. This version of the engine produces more low-rpm power than the smaller 4 cylinder L Series, but suffers from compromised high-rpm power due to the smaller valves/lower valve lifts required in the cross-flow NAPS-Z (Nissan Air Pollution System) cylinder head. LZ (competition) The "LZ" twin cam head was designed to give a power boost to the Datsun L series engine for competition purposes. The best way to increase output was to improve its breathing. The solution chosen was 4 valves per cylinder operated by two camshafts in a cam box. Combustion chamber valve angles were kept quite shallow to minimise gas flow interference from "twin in-cylinder vortices". The shallow angle 4-valve system, gives greatly improved cylinder fill through high valve lifts that can be used with large valve overlap periods. This system was later used by Suzuki on their GSX 1100R engines to great effect. There are two different LZ cylinder heads. The early head is the same thickness as a normal L series head. The engine using the first head was referred to as the L14 twin cam. There was no mention of Z in the title. This L14 twin cam head engine has flat exit side exhaust ports, the early 12 bolt rocker cover and the coolant discharge on the inlet side of the head. All early twin cam engines appear to have the 14 bolt rocker cover (6 for the cover and 8 for the bolt-in plug holders). Later engines use the full flat cover with six bolts to secure it. The LZ engine was built purely for Datsun/Nissan competition use. Engine size can vary between 1400cc (LZ14) in the PB110 "1200", 1600 cc in the PB210, 1800 CC in the 710 2.0 litres in the PA10 Stanza, to 2.2 liter in the 910 bluebird rally cars. The naturally aspirated LZ engines used 45 mm or 50 mm Solex carburettors depending on capacity. The LZ engine found its way into many categories, from "Datsun Works" rally cars, Formula Pacific, Group 4 (racing), Group 5 (racing) and Group C. In some Japanese racing classes the LZ engine is fitted with low compression pistons and a "T05B" turbocharger. These engines are electronically fuel injected. A very successful example of the LZ turbo was in the famous Japanese "White Lightning" Silvia and "Tomica" R30 Skyline, both driven by Hoshino in the mid 1980's. The LZ turbo engine was also used in the 1986 Nissan March 85G Le Mans car. http://en.wikipedia.org/wiki/Nissan_L_engine 28.10.2011 21:41:06 Nissan L engine - Wikipedia, the free encyclopedia Стр. 4 The LZ turbo engine was tuned to produce 570 PS at 7,600 rpm and 539 Nm at 6,400 rpm. The original LZ20B turbo engine used in the 1983 Nissan Silvia (S12) "White Lightning" Group 5 race car, produced 500 PS at 8,000 rpm. The LZ14 engine for the Formula Pacific race cars produces 205 PS at 10,200 rpm. For qualifying and non endurance events the LZ14 can be tweaked to produce 240 PS at 11,000 rpm. The LZ14 is naturally aspirated and has a 66 mm stroke and 87.8 mm bore (1,598 cc).
