摘要： PROBLEM TO BE SOLVED: To provide an indirect injection type internal combustion engine which freely performs heating and breaking inside a sub-chamber according to operation conditions of an engine, can control the temperature inside the sub-chamber at required high temperature in accordance with the operation conditions of the engine, and always retains favorable ignition from the starting of the engine to all driving ranges even in the case of driving under conditions of cryogenic temperature such as in cold climate areas, or driving using fire-retardant fuel, thus can perform a stable combustion.
SOLUTION: The indirect injection type internal combustion engine is provided with a high-frequency heating device and a controller. The high-frequency heating device has a high-frequency coil which is wound at a mouthpiece of the sub-chamber, and through which high-frequency current is passed from a high-frequency transmitter, and the interior of the sub-chamber is heated by the high-frequency coil. Then the controller controls energization and breaking to the high-frequency heating device according to the operation conditions of the engine including either engine RPM or the load on the engine, or both. The controller is constituted so that it energizes the high-frequency coil through the high-frequency transmitter when the operation conditions of the engine are at low-range revolutions or in the low-load ranges, that is to say, at or below constant rpm or load. Then the controller breaks the energization when the operation conditions of the engine exceed the constant rpm or load.

摘要： PROBLEM TO BE SOLVED: To make it possible to improve the fastness and durability and to be used for a long period by flame spraying silicon onto the surface of a glow plug containing Si-based ceramics as a base material to form an intermediate layer, and coating the surface with one type of alumina and zircon to form an outer layer. SOLUTION: A ceramic glow plug 1 flame sprays silicon onto the surface of a glow plug 2 containing Si-based ceramics as a base material to form a silicon intermediate layer 3. Further, zircon is flame sprayed on the surface of the layer 3 to form an outer layer 4. Instead of the zircon, alumina or mullite may be flame sprayed to form the layer 4. The silicon has thermal expansion coefficient similar to that of Si3 N4 or SiC, and its oxidation resistance is more excellent than those of tungsten or molybdenum, and its Young's modulus is smaller than that of oxide or Si-based ceramics, and hence its deformability is large.

摘要： PURPOSE:To realize accurate air-fuel ratio feedback control even if deterioration of a catalyst is started. CONSTITUTION:First and second O2 sensors 12, 13 whose output signals are suddenly changed by a theoretical air-fuel ratio are arranged upstream and downstream from a catalyst 11 for purifying exhaust gas. An ECU 20 smooths an output signal from the second O2 sensor 13 by a prescribed smoothing ratio and then compares this smoothed signal with a comparative voltage, so as to judge the air-fuel ratio of a gas engine 1. The air-fuel ratio of the gas engine 1 is feedback-controlled by this result and an output signal from the first O2 sensor 12. Moreover the ECU 20 detects the amplitude of the output signal of the second O2 sensor 13 at this time and corrects the comparative voltage so that the air-fuel ratio of the gas engine 1 may become rich according to the detected amplitude.

摘要： PROBLEM TO BE SOLVED: To eliminate the drop of a damaged part in a combustion chamber by forming a protrusion by an outer cylinder for internally mounting a glow plug having a heater in a base material, providing an opening smaller than the diameter of the plug on the inner surface, and allowing fuel to arrive at the end of the plug via the opening. SOLUTION: A glow plug 1 is internally mounted in an outer cylinder 2, and mounted at a predetermined angle θ at a cylinder head 3. The plug 1 is disposed to protrude into a combustion chamber 5 so as to arrive at a fuel injection area A from a fuel injection valve 4 in the state that the plug 1 is inserted into the cylinder 2. The cylinder 2 has a protrusion 2a protruding at an interval L from the end 1a of the plug 1, and a step 6 is provided at the inside of the end 2b. The opening 7 having a diameter D2 reduced from the diameter D1 of the plug 1 is formed. The end 1a of the damaged plug 1 can be held as indicated by a broken line.

摘要： PROBLEM TO BE SOLVED: To maintain seat part pressing force safely even at the time of a spring being broken by leading high pressure fuel gas to a valve seat part through the inside of a spindle from the rear of the spindle. SOLUTION: A gas fuel valve is so constituted as to lead fuel gas (a) of pressure Pg to a valve seat part 30 through the inside of a spindle from the rear of the spindle so as to obtain seat pressing force acting upon the spindle in the same way as the spring force of a compression spring 17 from the relation between the peripheral pressure and action area of the spindle. The spring force is set in such a way that the spindle presses the valve seat part 30 even in the case of no gas being led into the fuel valve. Sealing performance can thereby be ensured even through using a spring of small force. As a result, the whole injection valve can be miniaturized through the dimensional reduction of the spring. In addition, the abnormal outflow of gas fuel into a cylinder at the time of the spring being broken can be prevented, so that safety as the valve can be improved.
