PURPOSE:To prevent soot from being discharged into the atmosphere, by providing a soot collector in the exhaust system of a diesel engine, incorporating the thus- collected soot into the engine oil and then injecting the soot-oil mixture into the combustion chamber. CONSTITUTION:In an exhaust pipe 3 of an engine 1, is provided a soot-collector 5 having a cyclone and wire net to separate off soot from the exhaust gas. Some oil in an oil pan 13 is introduced into the thus-separated soot via an oil supply pump 12 and oil supply pipe 11. Resulting oil-soot mixture is then collected in an oil reservoir 14. Thereafter, the oil-soot mixture is mixed into the fuel supplied from an oil tank 17 through an oil feeding pump 16 and then injected from fuel injector valves 21 into the engine 1 via filters 18, 19, and fuel injector pump 20. Into the oil pan 13, fresh oil is always replenished from an automatic oil feeder 22 at a rate equivalent to the flowing-out rate of the oil from the pan 13. |
