Abstract
A method of converting a diesel engine to a natural gas engine comprising inserting a spark plug into a diesel fuel injector opening in a cylinder head; installing a throttle body on the diesel engine; installing a throttle body adaptor between a throttle body and an intake manifold of said diesel engine; and modifying a piston, whereby the compression ratio of said piston is decreased during operation of said piston. The method also includes installation of a waste gate and waste gate adaptor and a timing mask.
Claims2
A method of converting a diesel engine to a natural gas engine characterized by an intake manifold, a cylinder head having one or more injector openings which receive a fuel injector, and one or more pistons in corresponding cylinders, said method comprising:
- removing said fuel injectors from said openings;
- inserting a spark plug into each of said openings;
- installing a throttle body adaptor on said intake manifold;
- installing a throttle body on said adaptor, said throttle body having a throttle plate which responds to actuation of an accelerator pedal and opens to allow more air/fuel into the intake manifold;
- modifying said pistons to decrease the compression ratio in said cylinders during operation of said engine;
- and
- modifying said pistons to have a three-ring or four-ring piston assembly;
- and wherein said throttle body adaptor further comprises a flange and a hose, said hose engaging said flange and engaging said intake manifold.
A method of converting a diesel engine to a natural gas engine characterized by an intake manifold, a cylinder head having one or more injector openings which receive a fuel injector, and one or more pistons in corresponding cylinders, said method comprising:
- removing said fuel injectors from said openings;
- inserting a spark plug into each of said openings;
- installing a throttle body adaptor on said intake manifold;
- installing a throttle body on said adaptor, said throttle body having a throttle plate which responds to actuation of an accelerator pedal and opens to allow more air/fuel into the intake manifold;
- modifying said pistons to decrease the compression ratio in said cylinders during operation of said engine;
- and
- modifying said pistons to have a three-ring or four-ring piston assembly;
- and
- installing a waste gate and a waste gate adaptor on said diesel engine, said waste gate adaptor enabling a turbocharger to communicate with an exhaust manifold on said engine through said adaptor;
- wherein said waste gate adaptor has an orifice for connection to said waste gate and also has holes aligned with the exhaust manifold and turbocharger.
