Abstract
Internal combustion engine and method for buffering of combustion gases and fresh air in a storage tank and producing power, torque and other functions by consuming buffered gases from storage tank for improved efficiency, improved power and torque, reduced emissions, immediate response to increase or decrease power and torque requests, new and improved functionality, kinetic energy recovery, thermal energy recovery and increased ECM flexibility.
Claims18
A buffered internal combustion engine for reducing greenhouse emissions comprising:
- an insulated main gas storage tank formed of at least one container capable of holding high pressure gases, at least one internal combustion chamber defined by a bore in an engine block with piston slideably disposed therein and a cylinder head having at least one intake valve, one exhaust valve, a fuel admittance, zero or one ignition starter, and a valve controlling the entry and exit of high pressure combustion gas between the main gas storage tank and an internal combustion engine chamber wherein an insulated conduit couples said valve to main gas storage tank;
- wherein, the space between the piston at top dead center and the cylinder head is minimal;
- wherein valves are electronically or mechanically controlled;
- wherein at least one sensor provides control information to the ECM;
- wherein at least one chamber is able to produce and load high pressure combustion gas to the main storage tank, and at least one chamber is able to produce power from the main gas storage tank's high pressure combustion gas.
A method of operating a buffered internal combustion engine for reducing greenhouse emissions using gaseous or liquid fuel comprises the following steps repeated continuously until a stop command is received and completed:
- evaluating engine conditions;
- scheduling engine start if engine is off;
- setting tank system's current preferred ranges to the optimal pressure levels;
- comparing current pressure levels in tank system to preferred ranges and schedule corrective action if current pressure levels are outside the preferred ranges;
- comparing current speed or [load] power to the desired values and schedule increase or decrease of power or speed at the optimal efficiency and sensed urgency;
- scheduling a standby or stop of engine if a request from the operator is detected, or ECM determines its need;
- reevaluating parameters for a new group of cycles, and event triggers;
- assigning a function to each of the chambers, and recalculating parameters;
- running the engine as scheduled for the time or number of cycles calculated by executing the functions specified in each active chamber, and operating other engine components.
