Summary:

This paper reviews application of D-Cycle technology to compact tractor diesel engine for improving efficiency and power. The study considers design challenges that are presented for accommodating D-Cycle technology in engine. The paper also covers resolving those challenges with established technical solutions. The study focuses on modifying conventional compact 4-stroke diesel engine with the intention of keeping design changes to a minimum level for incorporating differential stroke technology. Designing of vertically splitting lightweight piston crown which can be smoothly engaged and separated from main piston body without any impact, stem rod which connects piston crown with rocker arm, split connecting rod and rocker arm which is actuated by extra actuating camshaft in addition of present valvetrain camshaft, are covered. Lubrication of additional actuating camshaft is done by extending existing oil galleries. The Paper also explains the necessity for gear-train layout modification. For ease of assembly of D-Cycle parts, an opening is given on the side of the crankcase which will be covered by an external cover during assembly. Paper also gives attention to choosing the correct assembly sequence for D-Cycle mechanism parts. In the end, the process of optimizing the D-Cycle mechanism by using kinematic analysis is also highlighted
