ABSTRACT
Modern world thrives on heat energy used in different forms.
Automobile industries is ever-growing industry.
95% of the automobile run on IC engines which are powered by fossil fuels.
Aim of thermal is to convert the heat energy to mechanical energy.
Efficiency of automobile is 30%.
Paper describes the potential IC engine.
To meet tomorrows challenges.
INTRODUCTION
Otto cycle theoretically represents best option for an IC engine cycle.
Fuel energy is converted to heat at constant volume , when fluid is at maximum compression.
Two technical modifications in 4-stroke to 6-stroke.
Six stroke engines captures the wasted heat from the 4-stroke Otto cycle , creates steam and cools engine by providing free power stroke.
Developed by BRUCE CROWER and MALCOLM BEARE.
BEARE DUAL OPPOSED PISTON 6-_STROKE ENGINE
6-stroke BEARE HEAD simply replaces the conventional 4- stroke engine cylinder head.
The BEARE HEAD utilizes an overhead short stroke Crank shaft and piston arrangement which open and closes inlet and exhaust ports leading through the upper cylinder liner.
The technology combines a 4-stroke engine bottom end with an opposite piston in the head working half the cylindrical rate of the bottom piston.
Head piston works in a ported cylinder closely resembling 2-stroke, thus 4+2=6.
Engine increases both torque and power output , better fuel economy , cleaner burning with reduced emissions.
Amount of power\torque generated by 35%.
