When overhauling Bare Engine, the Isuzu Engine must be replaced at the same time as the piston pin to restore its normal fit. The fit between the outer diameter of the Isuzu Engine and the small head hole of the connecting rod should have an interference of 0.10~0.20mm to ensure that the bushing does not rotate during operation. If the

1. Introduction to Bare Engine: Bare Engine are subject to the gas force of the piston pin and its own swing and the reciprocating inertia force of the piston group. The magnitude and direction of these forces are periodically changing. Therefore, Bare Engine are affected by alternating loads such as compression and tension.

(1) When this noise occurs, the Bare Engine can be idle and tested cylinder by cylinder. Then, the throttle is shaken from idle to medium speed, and a "click" sound can be clearly heard when the throttle is shaken. In the stop-fire test, there is an obvious cylinder-up phenomenon, and the noise can be sensiti

(1) There is a continuous and obvious knocking sound when accelerating suddenly, and the sound is like "clicking". (2) This sound can be heard at idle, but it is obvious at medium speed and not obvious at high speed. . When the temperature of the Bare Engine changes, the noise does not change a

For example, when cleaning carbon deposits by the soaking method, the cleaning fluid is not cleaned up, causing the Mitsubishi Engine to top the cylinder when restarting; for Bare Engine equipped with a variable intake duct system. If the cleaning agent flow rate is not properly matched with the speed of the Mitsubishi Engine, it may

This situation is usually caused by continuous injection of fuel by a certain cylinder injector of Bare Engine. Often before that, there will be difficulties in starting, idling jitter, black smoke from the exhaust pipe, and power reduction. After disassembly and inspection, it can be judged by observing the

(1) Is the air filter damp or attached with soil? Are there any water marks on the air filter housing and the intake pipe wall? (2) Check the Bare Engine oil to determine whether the Mitsubishi Engine cylinder has water in it. After water enters the Bare Engine, the oil around the Bare Engine cylinder head and the intake and exhaust v

Water in the cylinder (combustion chamber) of Bare Engine causes Bare Engine to bend or break. When the vehicle is driving on a road with water on the road, the Mitsubishi Engine will suck water into the cylinder. The water that first enters the cylinder quickly forms hydrated gas under the action of the

The Bare Engine is a rod-shaped component that connects the piston and the crankshaft. It transmits the force of the piston to the crankshaft, converting the reciprocating motion of the piston into the rotational motion of the crankshaft. The Mitsubishi Engine is a slender variable-section non-circular rod, w

The Bare Engine process is a precision hole processing process guided by the processing surface. Under a certain feed pressure, the processing allowance is removed by the relative movement of the tool and the part, and its cutting trajectory is a precision hole processing process with a cross grid. Mitsubishi Engine refers to

In recent years, with the continuous development of the automobile manufacturing industry, the automobile and parts manufacturing industries have become the largest and most important customers of the tool industry. As the "heart" of the car, Bare Engine also play an important role in the processing of the whole vehicle, and t

The reliability and durability of Bare Engine should not be too large. If the gap is too large, the lubricating oil will flow out of the gap and the connecting rod mechanism. Improper assembly of the crank connecting rod mechanism will affect the loss and cause oil leakage at the rear end of the crankshaft.

(1) Before installation, check whether the gap between the Mitsubishi Engine end and the edge meets the technical requirements. When installing the old ring, install the ring groove according to the original cylinder number and original order. When installing the Mitsubishi Engine, special tools should be used.

The piston slides at high speed along the cylinder wall under the action of lateral pressure. Due to poor lubrication conditions, friction loss is large and wear is severe. Generally speaking, about 40% of the friction loss on Mitsubishi Engine comes from the friction between the piston, piston ring and cylinder wall, not the

The pistons and connecting rods on Bare Engine are part of the crank-connecting rod mechanism, and together they form a piston-connecting rod group. It is a component with extremely high technical content in Bare Engine, and has extremely high requirements for the materials, metallurgical processes, heat treatmen

(1) When this noise occurs, the Bare Engine can be run at idle speed and a cylinder-by-cylinder stop test is performed. Then, the throttle is shaken from idle to medium speed, and a "click" sound can be clearly heard when the throttle is shaken. In the stop test, there is an obvious cylinder-up phenomenon, and the noise

The top of the piston is in direct contact with the high-temperature gas, which makes the temperature of the top of the piston very high. The piston slides at high speed along the cylinder wall under the action of lateral pressure. Due to poor lubrication conditions, friction loss is large and wear is serious. Generally speaking, about 40% of the friction loss on Bare Engine comes from the friction between the piston, piston ring and cylinder wall, not the car.
