Title:
【発明の名称】デュアル-シリンダ・エキスパンダ・エンジンおよび1サイクル2膨張行程を有する燃焼方法
Document Type and Number:
Japanese Patent JP2003517526
Kind Code:
A
Abstract:
An internal combustion engine is provided with an expansion cylinder and at least one combustion cylinder, preferably two or four combustion cylinders per expansion cylinder. An air-fuel mixture is ignited within the combustion cylinders to drive a combustion piston which, in turn, drives an engine crankshaft. The gaseous products of combustion are exhausted at a pressure substantially above atmospheric to an expansion cylinder wherein they are allowed to further expand against an expander piston to drive an expander crankshaft. Torque produced at the engine crankshaft and torque produced at the expander crankshaft are combined to drive vehicle wheels.
