3 hp 4 stroke internal combustion engine

For large marine engines, the ability to combine long stroke/bore ratios with low BMEP and low engine speed offers unparalleled efficiency and durability.

Two-stroke engines, while phased-out from most vehicle applications due to the challenges in meeting emission standards that were adopted in the 1990s and 2000s, continue to be the preferred powerplant option for many applications.

Noteworthy alternative combustion engine concepts include: Several alternative combustion concepts have either found niches in applications for which they offer clear advantages and/or have been explored as alternatives to the entrenched design. These advantages may include high thermal efficiency, high power density and the related compact size and light weight, or tolerance for low quality fuels. Yet, alternative engine designs can offer some potential advantages and continue to be explored. Internal combustion engines consisting of a piston reciprocating in a cylinder and connected by a connecting rod to a crankshaft-most commonly four-stroke diesel and spark-ignited engines-have become entrenched for many applications for at least a century.

These alternative designs include rotary engines, such as the Wankel engine, two-stroke engines, as well as six-stroke and split-cycle engines. Abstract: While the four stroke diesel and gasoline engines have been firmly entrenched for most applications, alternative combustion engine concept have been pursued that can offer improved efficiency, power density, and other potential advantages.
