Benefits of technology

The present invention relates to converting diesel engines to spark ignited natural gas engines for use in road HD trucks, stationary, marine, and locomotive applications. The invention provides a method for converting diesel engines to meet ultra low emission standards by modifying the engine's head, piston, and timing mechanisms. The invention also includes a throttle body adaptor and a waste gate adaptor for optimizing engine performance. The invention allows for the use of natural gas as a fuel for improved fuel efficiency and reduced emissions levels.

Embodiment Construction

[0021]Those skilled in the art will recognize that the steps needed to convert a diesel engine to an engine utilizing natural gas will depend on the specific type of diesel engine. For example, while a spark plug assembly must be inserted in all diesel engines for conversion, those skilled in the art will recognize that because some diesel engines are manufactured with waste gates, a waste gate adaptor will not be required for conversion. Likewise, because many diesel engines are manufactured with a timing mask, installation of such a device will not be required. For illustrative purposes, the present invention is described with reference to the Navistar 466 Engine (also known as the “old generation” or “legend” engine) and the Navistar 530 and 466E Engines (also known as the “new generation” engines). Thus, the present invention is not intended to be limited to conversion of the specific diesel engines described herein.

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.
