of the fuel forces piston 32 downwardly on its power stroke as seen in fig2 c when the piston is about half way down exhaust valve 24 opens to permit the burned gases to escape through exhaust port 20 shortly thereafter the downwardly moving piston 32 clears inlet ports 16 permitting scavenging air to once again be forced into the cylinder by the blower unit see fig1 as previously mentioned the diesel engine component of the power plant of the present invention basically comprises a modification of a conventional two stroke commercially available diesel engine in fact in one form of the invention the diesel engine component comprises a modification of a diesel engine sold by the detroit diesel corporation under the model designation 6v92 the term 34 conventional engine 34 as used herein means a standard commercially available diesel engine of the general character exemplified by the 6v92 engine manufactured and sold by the detroit diesel corporation as will become clear from the discussion which follows many of the features of the diesel engine component of the apparatus of the present invention the green engine are described in terms of changes to the commercially available detroit diesel engine for example the exhaust cam profile of the detroit diesel engine is specifically defined in table 1 of the specification see page 10a while the exhaust cam profile of the diesel engine component of the present invention is specifically defined in table 2 see page 10b similarly a comparison between the duration of time during which the exhaust valves are open in the diesel engine component of the present invention and in the detroit diesel.
