The small head of the Bare Engine is connected to the piston through the piston pin, and the big head is connected to the crankshaft journal. The size depends on the pressure-bearing area. The working temperature of the Bare Engine is 90. ~100℃, and the running speed is 3000℃~5000r/min. In orde

The correct selection of rough datum and the reasonable design of initial positioning fixture are crucial issues in the processing process. When positioning the side of the connecting rod, the rough datum positioning method of the connecting rod datum end face and the outer circle of the small head blank at three points and the outer circle

In addition to bending deformation, the fatigue accumulated from long-term work and the influence of strong external forces may also cause the connecting rod to break. The parts that are prone to breakage on the connecting rod are mainly the rod body where the bolts are installed and the position of the MG Roewe Maxus Engine. Du

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, a

When the Bare Engine is working, due to the swing and large force, the rod will bend and twist, the ellipse and cone will wear the inner holes of the large and small ends, and the Isuzu Engine bolts will be damaged. Bending or twisting of the Bare Engine will cause the piston to be skewed in the cylinder, resulting in wear

(1) Check the gap between the Bare Engine and check whether the gap between the Bare Engine is suitable for interference. (2) Put the piston in water and heat it. After the water boils, heat it for 5 to 8 minutes. (3) After removing the piston, quickly insert the small end of the connecting rod between the Isuzu Engine se

The reliability and durability of the work of Isuzu Engine should not be too large due to the gap between the cranks. If the gap is too large, the lubricating oil will flow out of the gap and the connecting rod mechanism will cause a large amount of oil leakage at the rear end of the crankshaft. ① During assembly, the t

Poor lubrication is the culprit for the breakage of the big end of Bare Engine. Due to poor lubrication, we can usually find traces of wear in other places of Bare Engine such as the inner wall of the cylinder. Common causes of poor lubrication include: lack of oil in Bare Engine, use of inferior engine oil, excessive tilt angle o

When the plane under the Isuzu Engine is aligned with the direction under the blade, the ammonium cutting should be stopped. At this time, press down the small end of the connecting rod to make the Isuzu Engine take off the ammonium knife to avoid corners and flares. When the diameter of the reamer remains unchanged, re-hingin

1. Bare Engine have high processing accuracy: especially some small and medium-sized through holes, the cylindricality can reach 0.001 mm. 2. Bare Engine have good surface quality: the surface is cross-netted, which is conducive to the storage of lubricating oil and the maintenance of oil film. 3. Isuzu Engine have

① Apply a thin layer of motor oil to the Bare Engine, and you should be able to push the Bare Engine into the bushing with your palm, without a sense of gap, in order to meet the requirements of tightness. ② Apply some motor oil to the Bare Engine, put it into the connecting rod bushing, and clamp the Bare

To better prevent the bushing from loosening, after pressing the bushing into the small hole of the connecting rod, the bushing can be squeezed outward with an awl to make the bushing fit tightly with the small hole. If the piston pin with increased repair size is replaced or the bushing needs to be repaired for other reasons, the bushi

The force on the connecting rod is directly related to the speed of Bare Engine. Generally, the design safety speed of small four-stroke general-purpose Bare Engine does not exceed 4000 rpm. Below 4000 rpm, the loads borne by Isuzu Engine parts are within an acceptable range. When the Isuzu Engine is overspeeding, these loads

If the piston pin with increased maintenance size is replaced or the Isuzu Engine needs to be repaired for other reasons, the Isuzu Engine should be machined. Make the piston pin and the Isuzu Engine achieve proper fit, and ensure that the fit clearance between the piston pin and the Isuzu Engine at room temperature is 0.003~0.008mm.

(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

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

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 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.

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

(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. (3) When the temperature of the Bare Engine changes, the noise does not change at

(1) Is the air filter damp or soil attached? 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 Bare Engine cylinder has water ingress. After water ingress, the oil around the Bare Engine cylinder head and the intake and exhaust valve seats

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.

(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. (3) When the temperature of the Bare Engine changes, the noise does not change at all. (4) After the cyli

Compared with forged steel connecting rods, the weight of titanium alloy connecting rods is significantly reduced, so the reciprocating inertia force of the connecting rod will be greatly reduced during the piston movement stage of Bare Engine. When companies test the speed of Bare Engine with different properties, they
