Combustion Characteristics of Low-Calorific-Value Gaseous Fuels in Small Gas Engine

On the Estimation of Power from a Diesel Engine Converted for Gas Operation – a Simple Analysis

In this paper, major factors influencing the power output from a gas engine are utilized to predict the power output from a diesel engine converted to gas operation using various gaseous fuels. The primary factors chosen are the gas calorific value, compression ratio, and molar changes due to combustion; leading to changes in peak pressures, peak temperature, turbo charger pressure and finally ...

Combustion and Emissions Characteristics of Biodiesel Fuels

Reformer Gas Application in Combustion Onset Control of HCCI Engine

Homogenous charge compression ignition (HCCI) combustion is spontaneous multi-site combustion of a nominally premixed air/fuel mixture that exhibits high rate of pressure rise and short combustion duration. To avoid excessive pressure rise rate and knocking, HCCI engines are fueled with highly diluted mixture using a combination of excess air and/or EGR. HCCI combustion is attractive due to ...

Low-Temperature Combustion of High Octane Fuels in a Gasoline Compression Ignition Engine

Gasoline compression ignition (GCI) has been shown as one of the advanced combustion concepts that could potentially provide a pathway to achieve cleaner and more efficient combustion engines. Fuel and air in GCI are not fully premixed compared to homogeneous charge compression ignition (HCCI), which is a completely kinetic-controlled combustion system. Therefore, the combustion phasing can be ...
