ABSTRACT:
A method of operating a diesel engine is disclosed. The method includes the step of sensing a temperature level associated with the engine. The method further includes the step of positioning the intake valve in the open position during an exhaust stroke of the engine if the temperature level is below a predetermined threshold value, whereby heated exhaust gases advance into the intake conduit during the exhaust stroke so as to heat intake air located in the intake conduit prior to the intake air advancing into the combustion chamber during a subsequent intake stroke. The method yet further includes the step of positioning the intake valve in the closed position during the exhaust stroke if the temperature level is above the predetermined threshold value, whereby heated exhaust gases are prevented from advancing into the intake conduit during the exhaust stroke. A diesel engine is also disclosed.
