Internal combustion engines

The Diesel Hybrid Combustion Engine Two main types of engines powering everyday machinery are diesel and gasoline internal combustion engines. Both vary on efficiency levels, but are still effective. Diesel engines have high efficiency levels, such as producing great amount of torque at very low rpms. They are also known for their fuel-efficient behavior and capability to produce low emissions. Their capability to produce power at an efficient rate with little wear

compressor that increases the pressure or density of air supplied to an internal combustion engine. This gives each intake cycle of the engine more oxygen, letting it burn more fuel and do more work. A turbocharger, or turbo, is a turbine-driven forced induction device that increases an internal combustion engine 's efficiency and power output by forcing extra air into the combustion chamber.This improvement over a naturally aspirated engine 's power output is due to the fact that the

What are Stirling Engines? Stirling engines are dynamic heat converters for converting heat energy in to work energy. They operate by the cyclic compression and expansion phases of gases and other fluids at different temperatures in such a way that heat energy is transformed in to mechanical work energy output [1]. Stirling engines primarily use air and other gases as their working fluids and are very unlike internal combustion engines. They require an external heat source for their operation and

Recirculation and forces unburned gas from the exhaust back into the engine making the car far more fuel efficient and environmentally friendly.  Unfortunately the next thing to follow was a serious toning down of the power of the engines.  The earlier thoughts were that bigger and more powerful were better, however these types of cars sent pollution caused by automobiles into an exponential growth.  The internal combustion engine vehicles that are on the road right now account for the vast majority

improved exhaust model includes the exhaust header of the car, turbulence unit, catalytic converter which basically changes the chemical composition of the exhaust emission gases, resonator, muffler, tail pipe etc. However, the entire setup includes the engine, fuel tank, radiator, self starting key, exhaust system etc. Several flanges has been provided to clamp the turbulence unit in between the exhaust pipe trailing from the exhaust header and the catalytic converter. Different designs of the turbulence

The diesel (internal combustion) engine has been a major source of power for transportation vehicles and industrial uses. The Australian railways have utilised diesel engines for regional and freight purposes since the early 1950 's. Despite the extensive history of the diesel engine, the efficiency of the modern internal combustion process ranges between 35% - 42%.[1] The losses in energy arise from heat losses and mechanical losses as illustrated in Fig 1.

on the activity of electric cars outside of the United States, so this section will center on what took place in the U.S. Electric Cars industry. In the U.S., electric vehicles were pervasive throughout the east coast, along with internal combustion and steam engines. Around 1900, 28% of cars in the United States were electric vehicles. It was marketed as a niche product and the primary target of such vehicles were females and professionals, specifically of upper class. Unlike the ICE, electric

propulsion systems, from the early attempts at propulsion to modern propulsion system such as propeller, internal combustion engine, ramjet engine and gas turbine. As this report will focus of aeronautical propulsion systems, rocket propulsion systems are almost exclusively involved in astronautics and will not be discussed. As an engineer will have to decide the best combination of engine and thrust device to attach to an aircraft. This report covers the technical developments in the advancement

market demand changed with skyrocketing oil prices. Fuel-efficient cars became a necessity, in the eyes of the consumer and in the eyes of the auto industry and the American government. For nearly a century, vehicles have been powered by internal combustion engines, which operate by

light terrestrial vehicles, and marine vehicles are a significant detriment to air quality, human health, and the environment. Due to the mechanical nature two stroke engines operations, engines running on fuel oil mixtures that have been blended from biologically based oils generate far less Green House Gas emissions than two stroke engines running fuel oil mixtures blended from more traditional petroleum based outdoor power equipment oil. Preliminary results of previous research support the hypothesis
