Opposed piston engines need to not be confused with flat engines , which are horizontally opposed with one particular piston per cylinder, and cylinder heads. It is also to be noted that for the duration of the later portion of the work cycle, past the point of maximum expansion, the gas is slightly compressed just before exhaust commences and this slight compression portion of the cycle of rotation, from around 45 degrees prior to bottom dead center of the principal piston to bottom dead center, permits the fuel to much more completely burn and thus, minimizes the presence of undesirable exhaust gas fumes.
The benefit is clear, for an engine may well be started with the crankshafts in a position exactly where the compression ratio is, say for example, 7 to 1. Right after it is running at high speed, a phase shift can then be created where the compression ratio increases to, say for instance, 11 to 1, offering a substantial raise in energy and efficiency in the engine output for the fuel being utilised.
Efficient combustion in the opoc engine is achieved by meticulously managing the exchange of exhaust gas with fresh air/fuel, by precisely controlling the opening and closing of the intake/exhaust ports, by utilizing our electrically controlled turbocharger to dynamically adjust system stress, and by employing state-of-the-art side-mounted direct-injection injectors to deliver highly atomized fuel into the combustion chamber which functions an innovative piston bowl style.
For example, evaluate a single-module 240 horsepower opoc engine with two equivalent engines from two worldwide marketplace leaders – the opoc engine occupies a containment space of .48 m3 / 16.95 ft3, whilst the engine from a prominent western manufacturer occupies .64 m3 / 22.six ft3 (33% larger), and the engine from a prominent eastern manufacturer occupies .7 m3 / …Read More
