Many high performance cars use carefully arranged air intakes and tuned exhaust systems that use pressure waves to push air into and out of the cylinders, making use of the resonance of the system. Two-stroke engines are very sensitive to this concept and can use expansion chambers that return the escaping air-fuel mixture back to the cylinder.
Animation of a two-stroke engine. A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes of the piston (one up and one down movement) in one revolution of the crankshaft in contrast to a four-stroke engine which requires four strokes of the piston in two crankshaft revolutions to complete a power cycle.
The 2-valve SOHC 2.0 L (1,968 cc) 19R was produced from 1974 through 1977. Cylinder bore and stroke was 88.5 mm × 80 mm (3.48 in × 3.15 in). Its dimensions are the same as of the 18R, but it featured TTC-V, Toyota's licensed version of Honda's CVCC stratified charge combustion system. Output is 80 PS (59 kW; 79 hp).
The Series 92 engines were introduced in 1974. [8] Compared to the Series 71 engines they were derived from, the Series 92 featured a larger bore of 4.84025 ± 0.00125 in (122.942 ± 0.032 mm) and an identical stroke of 5 in (130 mm) for a nominal displacement per cylinder of 92 cu in (1,510 cc), from which the Series 92 derives its name.
The engine code was changed from Hino's "GR100" to "G" for these cars. [5] The engine is a 1251 cc watercooled OHV inline-four with distant Renault origins and was originally developed by Hino for their Contessa passenger car. Bore and stroke are 71 mm × 79 mm (2.80 in × 3.11 in), maximum power 63 PS (46 kW) at 5500 rpm.
Glow fuel is a fuel source used in model engines – generally the same or similar fuels can be used in model airplanes, helicopters, cars and boats. [1] Glow fuel can be burned by very simple two-stroke engines or by more complicated four-stroke engines, and these engines can provide impressive amounts of power for their very small size.
The German company Bosch had been developing a mechanical GDI system for cars since the 1930s [44] and in 1952 it was introduced on the two-stroke engines in the Goliath GP700 and Gutbrod Superior. This system was basically a high-pressure diesel direct-injection pump with an intake throttle valve set up.
The engine has a displacement of 2.0 L; 121.9 cu in (1,998 cc) with a bore and a stroke of 3.38 in × 3.38 in (86 mm × 86 mm). [2] The compression ratio of the engine is 10.5:1. [2] The 2.0 L engine was offered by Dodge in the Dodge Caliber. Outside North America, the 2.0 was the base engine for the 2007 Chrysler Sebring and 2008 Dodge Avenger.
