Abstract:
A structure for preventing inlet of foreign material in the oil by-pass of the automotive engine is provided to remove the foreign material which is included in oil that is transferred to a bypass channel. A structure for preventing inlet of foreign material in the oil by-pass of the automotive engine comprises as follows. The oil enters to the oil cooler through the bypass channel without passing through the oil filter when the differential pressure of oil entering to the oil filter is over a certain pressure in the oil pump. A bypass filter(70) is installed at the bypass channel. The bypass filter filters the oil which flows to the bypass channel from the oil pump immediately. The bypass filter includes an outer filter(71) which has s hemi spherical filter body(71a), and an inner filter(72) which has a filter body(72a) that is installed inside the outer filter of the flat type.

A vehicle mass estimation method is provided to estimate mass of a vehicle by using variables measurable while the vehicle travels and to improve mass estimation reliability by estimating the mass of the vehicle under various traveling states of the vehicle. A vehicle mass estimation method comprises the steps of: measuring yaw velocity, speed, steering angle, and vertical acceleration of the vehicle(S110); estimating the mass of the vehicle by applying a rectilinear model algorism if the measured yaw velocity of the vehicle is below reference yaw velocity(S121,S131); estimating the mass of the vehicle by applying a transverse model algorism if the measured steering angle of the vehicle is over reference steering angle(S122,S132); estimating the mass of the vehicle by applying a vertical model algorism if the measured vertical acceleration of the vehicle is over reference vertical acceleration(S123,S133); judging whether the estimated mass of the vehicle is bigger than minimum mass and smaller than maximum mass of the vehicle or not, if the estimated mass of the vehicle is kept constantly for 15 seconds(S141); judging whether the estimated mass of the vehicle is bigger than minimum mass and smaller than maximum mass of the vehicle or not, if an average of the estimated mass of the vehicle is kept constant for 15 seconds(S142); judging whether the estimated mass of the vehicle is bigger than minimum mass and smaller than maximum mass of the vehicle or not, if the estimated mass of the vehicle is kept constant for 2 seconds; and finally estimating the mass of the vehicle by applying the mass of the vehicle estimated in each step, to an RLS(Recursive Least Square) method(S160).
Abstract:
An O-ring for an oil cooler of a CNG engine is provided to increase durability of the O-ring and to reduce manufacturing cost in comparison with the conventional O-ring made of aflas. An O-ring for an oil cooler of a CNG engine includes an inner ring(100) and an outer ring(110). The inner ring is made of a compressible and expandable material. The outer ring covers the outer part of the inner ring to protect the inner ring, wherein the outer ring is made of a metal material and has an opening(112) so as to cover only a portion of the inner ring. The length of the opening of the outer ring is larger than the maximum compression height(H) of the O-ring such that the outer ring is not overlapped when the O-ring is compressed.

PURPOSE: An injection pump governor is provided to prevent partial side wear of the slider member and abrasion of the pin member where the slider member is mounted. CONSTITUTION: An injection pump governor controls the injection volume of the fuel injection device by pushing a sleeve through the movement of a slider member(13), opening a fly weight member(11) and operating a control rack in accordance with the opening of the fly weight member. An injection pump governor comprises a stopper member(10) interposed between the fly weight member and the slider member. The stopper member has an end coupled to the fly weight member and the other end contacting the slider member, thus restricting motion trajectory of the slider member. The slider member is coupled to the fly weight member so that the slider member is rotatable centering from a pin member(15).
