The different ways to make an internal combustion engine work more efficiently

OPGCI: An Evolution that Revolutionizes the Internal Combustion Engine

Essentially all of them work the same way. A mixture of air and fuel is sucked into the engine, where it is compressed.

  • At high loads four-stroke GCI engines have to make calibration tradeoffs to maintain the mechanical integrity of the engine, sacrificing both efficiency and performance;
  • Credit is due under the terms of this license that can reference both the New World Encyclopedia contributors and the selfless volunteer contributors of the Wikimedia Foundation;
  • An engine has 351 cubic inches and 330 horsepower;
  • Intro To Car Engines —Cut-away images and a good overview of the internal combustion engine The Fuel and Engine Bible —A good resource for different engine types and fuels youtube —Animation of the components of a 4-cylinder engine youtube —Animation of the internal moving parts of a 4-cylinder engine Credits New World Encyclopedia writers and editors rewrote and completed the Wikipedia article in accordance with New World Encyclopedia standards;
  • In this engine, there are two cylinders that are 180 degrees apart for each pair of counter rotating cams.

The burning gasses expand, and then they are expelled from the engine. Click here for an explanation of the four cycles.

  • Engines running on a five-stroke cycle are up to 30 percent more efficient than an equivalent four stroke engine;
  • It is generally measured in liters L or cubic inches c;
  • This gives an engine almost equal chances to run as efficiently as possible at all speeds!
  • The Bourke engine's combustion phase more closely approximates constant volume combustion than either four stroke or two stroke cycles do;
  • Every other speed the engine has no chance to run as efficiently;
  • Gasoline Compression Ignition Delphi and Argonne have both demonstrated that gasoline can be combusted with a high compression ratio, under lean conditions and without throttling, and can be ignited without a spark plug.

Thermal efficiency is the percentage of energy taken from the combustion which is actually converted to mechanical work. Click here for a diagram of power losses.

Volumetric efficiency is the relationship between how much air and fuel has been taken into the cylinder, compared to how much air and fuel is required to fill the cylinder under normal atmospheric pressure. Volumetric efficiency is expressed in a percentage.

Another way to rate an engines performance is its horsepower to cubic inch ratio. An engine has 351 cubic inches and 330 horsepower. Hopes for a more efficient engine.

  • Gasoline engines are used in most other road vehicles including most cars, motorcycles , and mopeds;
  • They are generally quieter, more efficient and larger than their two-stroke counterparts.

Engines aren't very efficient. Luckily, people are always working on ways to improve the performance of engines. The last few years have really opened the door for more efficient engines with the improvement of computers. Computers now control almost every aspect of how new car engines run. The one thing that they do not control on your engine, that would have the most improving effect, is the valve timing. The cam is the brains of an engine.

It tells the engine when to fire its spark not all caseswhen and how long to breathe in and out. Since a cam can't change when and how long to do these things, an engine is setup to run most efficiently at one speed.

Every other speed the engine has no chance to run as efficiently. There are companies that are now trying to make engines with variable valve timing. There are a couple ways this will work, but the best is with solenoids that are computer controlled. The computer analyzes information and decides how to control the valve events. This gives an engine almost equal chances to run as efficiently as possible at all speeds!
