Why No Diesel Motorbikes ?
« Reply #25 on: 04/06/2009 12:20:28 »
The correct terminology of a diesel engine is a "compression ignition engine".
Bikes do not have suitable space and places by design constraint to put:
A. Injector rack
B.fuel filter (required to be checked)
C. A deliberate fuel pump

These three last points are massively critical requirements to operate a diesel engine with any reliability and efficiency for an economic market. So therefore are almost redundant for design purpose and impossible economically to include.

--added edited--

Another factor in design less seldom know is the safety requirement legislation for market in each country. Because of mounting more exposed both critical and complex parts the equipment of a motorcycle would require greater investment in safety technology and engineering, so hence the R&D costs to successfully make these extra parts safe under the enormously dangerous conditions of a motorcycles' operation is too much.

another factor is the control(use) of acceleration in the revolution band and burning speed of the fuels(diesel) energy yield is not the same as with petrol and again hence requires a different set of gear ratios in the gearbox not parts that can be interchanged or match that of the petrol for production cost.

The defining feature of the diesel engine is the use of the heat of compression to initiate ignition to burn the fuel, which is injected into the combustion chamber during the final stage of compression. This is in contrast to a petrol (gasoline) engine or gas engine, which uses the Otto cycle, in which a fuel/air mixture is ignited by a spark plug.
