The ignition coil has a cylindrical primary coil body (1) provided with a primary winding (4), a cylindrical core (3) formed from stacked metal plates and a secondary coil body (2) provided with a secondary winding (5), enclosing the cylindrical core. The ...

A process for controlling the heating of glow plugs in a diesel engine comprises emulating the thermal behavior of the plug on heating and cooling and using this information as control data for controlling the heating process. An Independent claim is also ...

The glow plug heating method has electrical energy supplied to the glow plug for heating it from an initial temperature to its required operating temperature, the amplitude of the heating energy dependent on the measured initial temperature of the glow plu...

The water pre-heating connection (6) has at least one heating rod projecting into the through-flow water channel. The rod contains heating and regulating elements. The heating rod (1) has no external thread, and is intended to be pressed into an unthreaded...

The connection method has a cylindrical carrier ring (4) of an electrically-conductive material fitted to the rod-shaped heating element (1) via a magnetic forming technique, before attaching the tubular carrier element (3) to the carrier ring. An Independ...

The glow plug heating control method detects the engine temperature in response to an engine starting signal, independent of the parallel initialization of the engine control, for providing a glow plug heating command when the engine temperature is below a...

The arrangement has an electrical heating device (1) arranged in the induction air channel (4) or in the air filter housing (3). The electrical heating device can be arranged between the combustion chamber inlet (2a) and the feed from the exhaust gas feedb...

Glow plug comprises a glow tube (8) containing an inner pole (7) which is connected to the tube via heating and control spirals (1, 2). The spirals are arranged in such a way that they are uniformly heated over a region of their length by the heat of the s...

The glowplug component connecting process involves joining the heating rod (1) to the glowplug body (2) by creating a radial force acting on the body , thus producing a central press seat between the rod and the body. The seat may be produced by crimping a...
