This produces a homogeneous charge: a homogeneous mixture of air and fuel, which is ignited by a spark plug at a predetermined moment near the top of the compression stroke. In a homogeneous charge system, the air/fuel ratio is kept very close to stoichiometric , meaning it contains the exact amount of air necessary for complete combustion of ...
Homogeneous charge compression ignition (HCCI) is a form of internal combustion in which well-mixed fuel and oxidizer (typically air) are compressed to the point of auto-ignition. As in other forms of combustion , this exothermic reaction produces heat that can be transformed into work in a heat engine .
The newer Honda stratified charge (lean-burn engines) operate on air–fuel ratios as high as 22:1. The amount of fuel drawn into the engine is much lower than a typical gasoline engine, which operates at 14.7:1—the chemical stoichiometric ideal for complete combustion when averaging gasoline to the petrochemical industries' accepted standard ...
In the homogeneous charge mode, the engine operates on a homogeneous air/fuel mixture (=), meaning, that there is an (almost) perfect mixture of fuel and air in the cylinder. The fuel is injected at the very beginning of the intake stroke in order to give injected fuel the most time to mix with the air, so that a homogeneous air/fuel mixture is ...
[33] [34] This engine could run on a variety of fuels (such as oil, kerosene, petrol or diesel oil) [35] and used a stratified charge principle whereby fuel is injected towards the end of the compression stroke, then ignited with a spark plug. The Cummins Model H diesel truck engine was introduced in America in 1933. [36]
A fuel tank (also called a petrol tank or gas tank) is a safe container for flammable fluids, often gasoline or diesel fuel. Though any storage tank for fuel may be so called, the term is typically applied to part of an engine system in which the fuel is stored and propelled ( fuel pump ) or released (pressurized gas) into an engine .
