The defining characteristic of a two-stroke engine is to fire (combust) every time the piston is at top dead center. This makes them highly power dense, but also notoriously makes two-stroke engines ...

Detroit Diesel built its well known two stroke engine for decades after getting its start during World War II, so why did it ...

Diesel engines, for all their rugged usefulness, can be tremendously polluting. They produce more NOx — nitrogen oxides-based emissions – than gasoline-fed cars, as well as more particulates, aka soot ...

There's an interesting bit of history behind the Chrysler 2.4 Tigershark engine. Chrysler established the Global Engine Manufacturing Alliance (GEMA) with Hyundai and Mitsubishi in 2002, a partnership ...

The 1999 phaseout of carbureted two-cycle engines from Lake Tahoe was aimed at reducing the amount of gasoline pollution at the lake. But the regulation passed by the Tahoe Regional Planning Agency ...

Like the trucks themselves, there also are many engines included in the long, rich history of Ford pickups, one of the biggest being the Power Stroke line of diesel engines. Some are iconic, ...

The two-stroke gasoline engine was once a marvel of engineering, offering up huge doses of power in small and lightweight packages. Unfortunately, gas two-strokes also burn oil by design, making them ...

Rotary engines have an aura of cool. In games of Top Trumps, the V12 might have been king, but a rotary was a joker, a wild card. A lack of mainstream success no doubt contributes; there are reasons ...

ABSTRACT Because of todays new emissions legislation, a new 45cc Husqvarna trimmer/clearing saw power head was needed. When reducing emissions in a conventional two-stroke engine or a stratified ...

The performance characteristics of a naturally aspirated two-cycle engine can be predicted with an unsteady gas dynamics analysis of flow through the crankcase and cylinder; such an analysis provides ...
