Fuel supply to EGR gases in a lean-burn auto-ignition i.c. engine

Fuel is added by an injector 28 to the intake air and, to promote lean burn and auto-ignition at low engine load, fuel is also added by an injector 50 or by carburation (fig.1) to exhaust gas which is recirculated to the engine combustion chamber 10 via an external EGR pipe 30 in which the fuel is vaporised. It is ensured, eg by overall lean burn operation, that air is present in the EGR pipe 30 to mix with the vaporised fuel and the length of the EGR pipe 30 after the injector 50 (or carburettor) is extended to produce a substantial quantity of partial oxidation products and so that the duration of combustion at optimum spark timing is reduced by at least 10%. The exhaust gas may be stratified on entry to the combustion chamber 10. A controlled air supply 58 may be added to the recirculated exhaust gas and a high voltage wire 60 may ionise the exhaust gas/fuel mixture to increase the production of fuel radicals. Ignition in the combustion chamber 10 may be effected by compression at low ...

Control Apparatus for an Internal Combustion Engine Capable of Pre-Mixed Charge Compression Ignition

An electric control device 70 is applied to an internal combustion engine 10 capable of a pre-mixed charge compression ignition combustion in which air-fuel mixture gas including air and fuel injected from an injector 37 is formed in a combustion chamber 25 , and the air-fuel mixture gas is self-ignited to be combusted by compressing the air-fuel mixture gas during a compression stroke. The electric control device injects high pressure fluid such as air from the air injection valve 38 into the air-fuel mixture gas at a predetermined acting timing within a compression stroke prior to fuel pyrolysis starting timing to enhance the temperature un-uniformity of the air-fuel mixture gas. This enables the temperature un-uniformity of the air-fuel mixture gas at the fuel pyrolysis starting timing to become larger than the temperature un-uniformity of the air-fuel mixture gas at the fuel pyrolysis starting timing obtained only by simply compressing the air-fuel mixture gas during the compression stroke. As a result, the combustion is moderated and the combustion noise is reduced.
