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...

A two-stroke diesel engine is a diesel engine that uses compression ignition in a two-stroke combustion cycle. It was invented by Hugo Güldner in 1899...

piston engine (e.g. two-stroke engine, four-stroke engine). "Stroke length", the distance travelled by the piston during each cycle. The stroke length...

Two- and four-stroke engines are engines that combine elements from both two-stroke and four-stroke engines. They usually incorporate two pistons. The...

A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft...

six-stroke engine is one of several alternative internal combustion engine designs that attempt to improve on traditional two-stroke and four-stroke engines...

The Saab two-stroke was a two-stroke cycle, inline, two cylinder, and later three cylinder engine manufactured by Swedish automotive manufacturer Saab...

use in crankcase compression two-stroke engines, typical of small gasoline-powered engines. Unlike a four-stroke engine, the crankcase of which is closed...

The five-stroke engine is a compound internal combustion engine patented by Gerhard Schmitz in 2000. The goal of the five-stroke engine is to achieve higher...

Power Stroke, also known as Powerstroke, is the name used by a family of diesel engines for trucks produced by Ford Motor Company and Navistar International...

configurations of the various bore/stroke ratio: A square engine has equal bore and stroke dimensions, giving a bore/stroke value of exactly 1:1. 1953 – Ferrari...

opposed-piston engines include Cummins, Achates Power and Fairbanks-Morse Defense (FMDefense). Compared to contemporary two-stroke engines, which used a...

two-stroke power valve system is an improvement to a conventional two-stroke engine that gives a high power output over a wider RPM range. A stroke is...

engines use 180 degree crankshafts. Two-stroke engines typically use a 180 degree crankshaft, since this results in two evenly-spaced power strokes per...

360 uses a 256 cc (16 cu in) two-stroke engine. In 1980, Suzuki began production of a 543 cc (33 cu in) four-stroke engine, which was introduced in the...

small air conditioning compressor. Engine braking in a premix two-stroke engine can be extremely harmful to the engine, because cylinder and piston lubricant...

on two-strokes for longer than most. Their first four-stroke engine was the SOHC F8A, which appeared in 1977. Suzuki continued to offer a two-stroke engine...

a piston engine that surrounds the crankshaft. In most modern engines, the crankcase is integrated into the engine block. Two-stroke engines typically...

Reed valves are commonly used in high-performance versions of the two-stroke engine, where they control the fuel-air mixture admitted to the cylinder...

the extremely widely used crankcase-compression two-stroke petrol engine, as used for small engines from lawnmowers to mopeds and small motorcycles....

a variable compression ratio engine. Gasoline engines have a limit on the maximum pressure during the compression stroke, after which the fuel/air mixture...

George Brayton in 1873. Most petrol engines use either the four-stroke Otto cycle or the two-stroke cycle. Petrol engines have also been produced using the...

Scavenging is equally important for both two-stroke and four-stroke engines. Most modern four-stroke engines use crossflow cylinder heads and valve timing...

In internal combustion engines, a split-single design is a type of two-stroke where two cylinders share a single combustion chamber. The first production...

was a Scottish engineer who designed the world's first successful two-stroke engine in 1878 and patented it in England in 1881. He was a graduate of Anderson's...
