Abstract

The Electrically-assisted internal combustion engine is a system with a high-torque electric motor connected to the engine crankshaft allowing stationery vehicles to utilise the excess electrical power used during their normal operation, to allow engine-idle without using any hydrocarbon fuels, thus avoiding expense and unnecessary pollution. When the vehicle idles for a set period of time, eg 15 seconds, the electric motor is activated by the engine management system to turn over the engine and all its functions thereby ensuring lubrication, cooling etc. On pushing the accelerator pedal the engine restarts. The electric motor may be powered by a dedicated or an enlarged battery system. If the battery runs low after extensive "idling", the engine will cut in automatically.

Description

I
Electrically-assisted Internal Combustion Engine(ICE).
I-An ICE produces far too much electricity for its own needs when in power. This application uses an electric motor(EM), linked to the J.C.E. unit, which is activated by the vehicle's own Electronic Management System/Computers when the vehicle's ICE sits at an idling speed for a specific short period of time (say 15 seconds). The EM will automatically cut in and instead of the ICE idling, not tumin the drive-train, but still consuming large amount of Hydrocarbon fuels, the EM (which will be running from electricity from either a dedicated or an enlarged battery system) will be turning over the engine only and all its functions (oil pump etc) to ensure lubrication! cooling etc'. The normal format can be seen extensively in iriner-uiLit:s and on motorways in rush-hour when thousands of ICE-powered cars are seen idling in queues, but going nowhere.
2-On either the ICE or the electrical-turnover system operating, the vehicle's alternator will charge-up the battery system. Under ICE the battery will gain charge, but under the EM system it will lose power slowly, but withthe new-generation of batteries emerging this will have even less effect.
3-On pushing the accelerator peddle the ICE will automatically re-activate and this will take over the main source of power, driving the engine and the drive-train, thus maximizing fuel usage, with all the inherent benefits.
4-The system will not be expensive to install either factry-fifted when new, or else retrospectively on cars that are already on the road.
5-For air-con the hot-water circulation can be maintained to allow heat-exchange to operate.
6-On the battery running low on power after extensive idling then the ICE will automatically cut in.
7-The results of the use of this system will result in a considerable reduction in vehicle costs and fuel usage, and have a considerable benefit to the environment in Air and Noise Pollution.

Claims (1)

  1. I-The Electrically -assisted internal combustion engine utilises the excess electricity produced when in the internal Combustion Engine (ICE) is in power mode. This application uses a high-torque electrical motor (EM), linked to the ICE unit, which is activated by the vehicle's own Electronic management System/computers when the vehicle sits at an idling speed for a specific short period of time (say 15 seconds). The EM will automatically cut-in and instead of the ICE idling, not turning the drive-train, but still consuming large amounts of Hydrocarbon fuels, the EM (which will be running from electricity from either a dedicated or an enlarged battery system) will be turning over the engine only, and all it's functions (oil pump etc.) to ensure lubrication/cooling etc. Due to valve timing related to the opening and closing of the valves, a vehicle's engine can actually be turned over by hand, thus illustrating how low the resistance is and how pertinent this system is. The normal format can be seen extensively in inner-cities and on motorways in rush-hour when thousands of ICE powered vehicles are seen idling in queues, but going nowhere.
    2-On either the ICE or the electrical-turnover system operating, the vehicle's alternator will charge-up the battery system. Under ICE the battery will gain charge, but under the EM system it will lose power slowly, but with the new generation of batteries emerging eg the Double Carbon, this will have even less effect.
    3-On pushing the accelerator peddle the ICE will automatically re-activate, via the electronic fuel systems found in modern vehicles, and this will take over as the main source of power, driving both the engine and the drive-train, thus maximizing fuel usage, with all the inherent benefits. The EM powers the turnover of engine only, not the drive train, which uses considerably more power, as is seen in Hybrid vehicles. Using the vehicle's standard system with no serious alterations, this avoids the weight and future expense/ availability problems of additional batteries as used in hybrid systems. This system is applicable to both petrol and diesel powered vehicles.
    4-The system will not be expensive to install either factory-fitted when new, or else retrospectively on vehicles that are already on the road.
    5-For air-con the hot-water circulation can be maintained for a certain period of time to allow heat-exchange to operate.
    6-On the battery running low on power (gauged by automatically monitoring the amperage) after extensive idling, then the ICE will automatically cut-in.
    7-The results of the use of this system will result in a considerable reduction in vehicle costs and fuel usage, and have a considerable benefit to the environment in Air and Noise Pollution.
