Does the Qingling Isuzu 4k engine have a timing belt

1. Hello, dear! It is a timing belt. The Isuzu dmax0t engine is not a timing chain, but a timing belt. First, the timing belt is an important part of the engine gas distribution system and is a kind of transmission component. The function of the timing belt is to ensure the accuracy of the intake and exhaust time by connecting with the crankshaft and cooperating with a certain transmission ratio.

2. Adjust the tension wheel, there is a scale in the middle, just adjust it to the middle. It's better to go to the repair shop to change this thing.

3. However, do not tighten it for the time being to ensure that the tightening wheel fittings can move freely. After assembly, it must ensure that the camshaft timing pulley and the fuel injection pump timing pulley.Multiple teeth and misaligned teeth are not allowed between the crankshaft pulley and the camshaft pulley, and bending the timing belt fittings is absolutely not allowed during the assembly process.

4. It's on time. According to the official website of Jiangxi Isuzu Automobile Co., Ltd., the Ruimai pickup truck produced by the company adopts timing belt transmission, so it is timing. The company was founded in April 2013.

5. Many trucks have timing belts, but diesel trucks do not have timing belts. Generally, they are internal timing gears, crankshaft wheels drive idlers, and idlers drive oil pump wheels and camshaft teeth.

6. Align the notation of the camshaft timing gear with the notation on the valve chamber cover. Alict the crankshaft timing gear mark with the front cover mark. Install the timing belt in turn, such as crankshaft timing gear, water pump pulley, idler, camshaft timing gear and pulley pulley pulley.

Isuzu diesel 4kh1_tc idling trembling, 1000 rpm is the most shaking, refueling to 1500 rpm does not shake, 3 cylinders when the cylinder is broken...

The engine carbon accumulation is serious. The most common cause of idling jitter is excessive carbonisation of the throttle valve or fuel nozzle.

The second is to see whether the idling jitter is an intermittent irregular jitter; the third is that in the jitter process, the idling speed is unstable. If the speed pointer is also swinging up and down during idling, it means that there is something wrong with the car.

Excessive carbon accumulation in the engine: When there is too much carbon accumulation inside the engine, the gasoline ejected by the fuel nozzle of the starting vehicle will be absorbed by a large amount of carbon accumulation, resulting in the mixture being too thin and difficult to start.The vehicle is easy to start only when the carbon-absorbed gasoline is saturated. Solution: It is recommended to clean the engine carbon frequently.

Is the 4kh1 engine authentic Isuzu?

[Pacific Automobile Network] It's not. In terms of engine selection, the whole series of Qingling TAGA is equipped with a 0T, model 4KH1CT5H1 Isuzu technology diesel engine, which adopts high-pressure common rail technology, and the injection pressure can reach 1800bar.

No. In terms of engine selection: The whole series of Qingling TAGA is equipped with 0T, model 4KH1CT5H1 Isuzu technology diesel engine, which adopts high-pressure common rail technology injection pressure up to 1800bar.

kh1 engine is imported, which adopts Denso high-voltage common rail technology, and the torque of the low-speed section is adjusted, which corresponds to superior overload and hill climbing performance.

As a brand focusing on pickup trucks, Isuzu perfectly combines practicality and innovation. The new N series is equipped with Isuzu's new 4KH1-TC engine, with an output power of 130 horsepower, adopts electronically controlled injection, medium-cooled supercharging technology, and has a supercharger with cooling device, and this The cost performance of the car is also super high.

4kh1ct6h1 engine precautions

It is recommended that any engine oil should not exceed 10,000 g Inside, otherwise you will change the life of the engine to the maintenance cycle. The new car of Daka Guoliu is equipped with a 0T diesel engine code-named 4KH1CT6H1, with a maximum power of 103kW and a maximum speed of 140km/h. According to different versions, the declared value of fuel consumption per 100 kilometers is divided into 4L and 8L.

kh1ct6h1 In terms of unique technology, double vortex turbocharging technology, in-cylinder direct injection technology, DVVT, piston spray cooling technology, two-stage variable displacement oil pump technology, etc. are all adopted on this high-power engine.

The only drawback is the style of the rim, which lacks a trace of sharpness. Due to design defects, the engine is born with idling jitter.

Loosen the motor fixing screw and the belt tightness adjustment screw. Push the generator against the engine to make the distance between the pulleys the shortest, and then straighten the belt sleeve. Adjust the tightness of the belt to the appropriate level, and tighten the engine fixing screw and adjustment screw.

When the compression of the engine is terminated and the piston reaches the apex of the stroke, the ignition system provides high-pressure sparks to the spark plug to compress the mixed gas in the cylinder. This time is the point The fire is on time.

Turn the crankshaft, observe the observation hole on the transmission housing, so that the scale line on the flywheel is aligned with the fingering on the housing. At this time, the engine cylinder piston is placed in the timing position. Rotate the camshaft, as shown in the figure below, so that the marking of the timing gear on the camshaft is flush with the bottom of the valve chamber cover.

The timing mark on the flywheel is used to ensure the mechanical timing of the engine - of course, it also needs to be coordinated with the timing mark on the camshaft drive wheel at the same time to effectively ensure the timing of the engine. In fact, the "time" we usually call has two meanings: ignition timing and gas timing (in fact, it should be called gas phase).
