Abstract:
There is provided a leakage detection apparatus that can accurately detect a leakage condition in an internal combustion engine having a cylinder resting function. An ignition plug provided in the combustion chamber of a cylinder is made to generate an ignition signal at least once when based on an instruction from a cylinder resting control unit, a fuel injection valve and a valve driving mechanism are stopping the operation thereof; the leakage condition of the ignition plug is detected based on an output signal generated by an ion current detection circuit at a timing other than the timing when ignition discharge is caused.
Abstract:
Disclosed is a spark plug arc intensifier system that influences the arc of the spark plug at any given performance of the gasoline engine. The intensifier system consists of a microcomputer that applies an additional signal to the lead-in wire coming from the transformer coil of the engine to influence the intensity of arc of the spark plug. This system results in a complete burning of the air/fuel mixture that is prevalent at the time of combustion. This system then results in a cleaner environment, less fuel consumption and a more powerful performance of the engine.
Abstract:
An apparatus and method are disclosed for reducing peaks of operating power drawn from a power source by a multi-channel system. Each channel of the system drives a load and demands operating power from the power source in an intermittent manner. Power is supplied to the multi-channel system from the power source. Operating power from the power source is drawn in an intermittent manner into each of two or more channels of the multi-channel system. The drawing of the operating power is by the two or more channels so that occurrences of peak operating power launched in a first channel do not fully overlap the occurrences of peak operating power in a second channel.
Abstract:
The invention relates to a method for operating an ignition device for a spark plug (ZK) of a motor vehicle, in which device the series connection of the primary winding (PW) of an ignition transformer (ZSP) and of a controllable switching element (IGBT) is connected in parallel with an adjustable energy source (EQ), and in which method, in order to store energy in the magnetic field of the ignition transformer (ZSP) both the energy source (EQ) and the switching element (IGBT) are actuated. In a manner according to the invention, the energy source (EQ) supplies a voltage (VSupply) continually increasing starting from 0V and limited to a maximum value, or a current with an increase rate limited to a maximum value.
