TECHNOLOGY OVERVIEW

Micro-Combustion creates a 10-12% improvement in fuel efficiency by utilizing lost energy from engine exhaust gasses i.e. Waste Heat Recovery. Cavitation Ignition Bubble Combustion Technology, AKA Micro-Combustion, utilizes implosion combustion of millions of microscopic cavitation bubbles to overcome friction with highly efficient homogeneous charge compression ignition. Our fluid coupled, integral torque converter and micro-combustion overcome friction by eliminating cumbersome reduction/transfer gears, bearings and an inefficient, mechanical torque converter.

INTRODUCTION

Engines Typically waste about 30% of the energy that is input to them through their exhaust. The lost exhaust energy that is leaving the engine system can be used to power an auxiliary turbine that will spin the CBIC waste heat recovery machine. This mechanical force will generates microscopic cavitation bubbles in the cavitator stage. The cavitator creates cavitation bubbles through negative pressures and mechanical forces, utilizing both the entrained air in the system, and input air from the compressor out stage of the engine’s turbocharger. This is accomplished by a check valve and a solenoid valve that actuates when conditions are right to add needed combustion oxygen to the system. A simple algorithm controls the opening of an orificed air inlet line based on entry conditions of differential pressure and power desired will allow for control of the power output by controlling combustion air. The oxygen introduced into the system enhances combustion of the cavitation bubbles. The air-fuel-cavitation bubble mixture will be under negative or very low pressures as it makes its way from the input side to the output side of the machine. The increasing pressure on the output turbine side of the machine will cause the bubbles to implode and the resulting combustion energy creates the combustion and expansion in the fuel. This combustion energy will then be harnessed by the output turbine to transmit power to an output shaft that can turn an engine crankshaft and add torque to the system or operate a generator that can charge batteries.

APPLICATION OF THE TECHNOLOGY

To address the need for a fuel economy bridge to Zero Carbon emissions for:

• Commercial Vehicles – Retrofit possibility for 2.5 Million vehicles, ~250,000 OEM engines/yr.
• Off-Highway Equipment - Retrofit possibility for 7.9 Million units, ~435,000 OEM engines/yr.
• Gensets - Retrofit possibility for 7.7 Million units, ~400,000 OEM engines/yr.

Off-Highway and Genset markets are projected to grow by 50% in the next 10 years. A further development opportunity exists to generate electricity to charge batteries in a hybrid application. There is no waiting for regenerative braking to charge batteries because Micro-Combustion will charge them while driving in normal conditions, enhancing battery-powered operating range and flexibility.

It is hopeful that this technology can be developed into a highly efficient, stand alone engine and we will extend the patent to cover this eventuality.
