摘要： PURPOSE:To recover high exhaust gas energy by connecting either a compressor or a turbine of more than two super chargers, or both of them in series, and also by connecting a rotating shaft of at least one super charger with the crank shaft of an engine. CONSTITUTION:In a two stage super charging system, after exhaust gas which is exhausted from an engine main body 10 through an exhaust pipe 12, has driven high pressure turbines of an exhaust gas high pressure stage turbo super charger 21, it drives turbines of an exhaust gas low pressure stage super charger 22. And after atmosphere which has been compressed by a compressor of the low pressure stage super charger 21, is cooled by an intermediate cooler 23, and is furthermore compressed by a compressor of the high pressure stage super charger 21, and then is fed into an intake pipe 13 through an intake air cooler 24. In the above said system, a rotating shaft of a low pressure stage super charger 31 is connected with a crank shaft of the engine main body 10 through a gear train 32. Then the surplus turbine output is enabled to return to the crank shaft 11 by way of the gear train 32 so as to obtain the high recovery of exhaust gas energy.

摘要： PURPOSE:To prevent a piston lower part from being cooled as well as to reduce a loss of friction, by installing a heat insulating layer in position between a piston crown and the piston lower part, while installing a cooling space for a flow of lubricating oil, inside the piston crown. CONSTITUTION:Cooling space 56-58 are installed in the inner part of a piston crown 52, making lubricating oil flow from an oil inlet 54 to an oil outlet 55 by way of a peripheral cooling part 56, a passage 58 and a central cooling apart 57, thus the piston crown is cooled. And, a heat insulating plate 61 and a heat insulating tube 62 are installed in space between the piston crown 52 and a piston lower part 51. With this constitution, the piston crown 52 is cooled, lowering its surface temperature and reducing a degree of NOx content to be produced, while cooling of the piston lower part is checked and viscosity of the lubricating oil on the surface is reduced to some extent without entailing any drop in temperature of a sliding surface 59 and, what is more, a loss of friction is reduced.

摘要： PURPOSE:To decrease the coefficient of dynamic viscosity of lubricating oil on the inner surface of a liner part and to reduce a friction loss between a cylinder and a piston, by a method wherein, in a device provided at the outer periphery of a liner part with a water cooling chamber, the thickness of the liner part is so formed that its lower part is thicker than its upper part. CONSTITUTION:Cooling water, discharged from a cooling water 21, flows to the lower part of a cooling water jacket 51, and after it cools the outer surface of a liner part 50, the cooling water incomes to a cooling water reservoir 24 of a cylinder head 13 through a communicating port 23 formed in an upper part. Thereafter, the cooling water flows to a thermostat 27 through a piping 26 by means of a cooling water outlet pipe 25. A part thereof further flows through a radiator 28 and a piping 29, and the remaining part flows to a cooling water pump 21 through a bypass piping 31. In this consitution, the thickness of the liner part 50 formed to the interior of a crank case 11 of a point on the the liner part increases the further downward along the liner part this point is situated. This causes the width of a cooling jacket 51 of this point along its surface to decrease the further downward along its surface this point is situated, resulting in the possibility to prevent cooling of the lower part of the liner part 50 to achieve a desired purpose.

摘要： PURPOSE:To improve intake efficiency and prevent a decrease of mechanical efficiency, by allowing cooling water, from a cooling water pump, to first flow into a cylinder head while the cooling water, after it is further heated, to flow into a water jacket in a cylinder block. CONSTITUTION:Cooling water, delivered from a cooling water pump 21, is allowed to flow first into a cylinder head 13, and outflowing cooling water from there, after it is heated by exhaust in a cooling water passage 43 of an exhaust pipe 42, is allowed to flow into a cooling water jacket 22 in a cylinder block 11. In this way, an engine prevents both intake efficiency from worsening due to a temperature rise of intake air and mechanical efficiency from decreasing due to overcooling of a cylinder.

摘要： PURPOSE:To reduce friction loss between a piston and a liner by dividing the liner cooling part of a crankcase into an upper part which cools water and a lower part which cools lubricating oil and changing the supply system of the lubricating oil cooling part in accordance with engine load. CONSTITUTION:The liner cooling part of a crankcase 11 has a partition stage 51 inside, by which the liner cooling part may be divided into a water cooling lower part 52 of the liner and a lubricating oil cooling upper part 53 thereof. There are provided both a passage in which lubricating oil is carried into a main gallery 46 via an oil pump 42, a filter 45 and an oil cooler 44, and a passage 60 in which lubricating oil is fed back to the oil pan 33 from the lower part 53 of the liner. When an engine generates a maximum output, a controller 62 fully opens electrically powered valves 54 and 59 and fully closes other electrically powered valve 57. Temperature of the lower part 57 of the liner is then increased because the part is heated by hot lubricating oil which has not passed through the oil cooler 44. At the low load time of the engine, the controller fully closes the valves 54 and 59 and fully opens the valve 57 and all lubricating oil will be sent into the gallery 46.

摘要： PURPOSE:To reduce the frictional loss between a piston and the lower end of a liner so as to improve the fuel consumption by providing a notch in a groove form at a part of the inner surface of the liner to the direction of a piston pin. CONSTITUTION:The lower end of a liner 12 is cut off to the height of L2 only to the axial direction of a piston pin 17 to make a notch 30. The height L2 is higher than the position of a piston pin 17 but is lower than the position of the lowermost piston ring 16. A force acting on the piston pin 17 to the direction normal to the pin axis is born by the portion of the liner 12 where no notch is available, and as the notch 30 is free from coming in contact with the piston 14, the frictional loss is reduced by that much. In addition, as the notch 30 is still positioned below the lowermost piston ring 16 even if the piston comes down to a bottom dead center, the sealing action of the piston ring 16 will never be impaired.

摘要： PROBLEM TO BE SOLVED: To check the presence or absence of smoke for the collected gas via the smoke sensors by preparing a smoke guiding main pipe having the intake means and collecting always and properly the gas from the storage sections via the branch pipes of the main pipe. SOLUTION: A smoke guiding main pipe containing the blowers 6a to 6c always and properly collects the gas from every storage section via its branch pipes 4a to 4c. The smoke sensors 3a to 3c check the collected gas whether they contain the smoke. If the smoke is detected in a certain multistage section, the valves 7a (7b, 7c) of branch pipes 4a (4b, 4c) of the relevant section are properly opened and closed and accordingly a smoke emitting section is specified. For instance, the presence or absence of smoke is checked in each section by opening and closing the valves 7a (7b, 7c) when the smoke is detected in the certain multistage section. Furthermore, the guide pipes 8a to 8c are prepared to guide the gas to the detectors 3a to 3c from the upper end of the main pipe. Thus, the smoke is accurately detected.
