Abstract
A compression ignition type engine comprising a combustion pressure sensor arranged in the combustion chamber, wherein whether defective combustion is occurring or not is judged from a change in the combustion pressure and the air-fuel ratio is made larger when it is judged that defective combustion is occurring.
Claims19
A compression ignition type engine comprising:
- a combustion chamber;
- means for detecting an increase in an amount of inert gas in the combustion chamber over a range to a certain amount, wherein an amount of production of soot gradually increases over the range and peaks at the certain amount, and detecting an increase in the amount of inert gas in the combustion chamber beyond the certain amount, wherein a temperature of fuel and surrounding gas at the time of combustion in the combustion chamber decreases such that an amount of production of soot decreases;
- means for providing an amount of inert gas to the combustion chamber that is greater than the certain amount;
- defective combustion judging means for judging whether defective combustion is occurring;
- and
- control means for controlling one of an air-fuel ratio and fuel injection timing so that combustion becomes good when defective combustion is occurring.
