How about Dongfeng Tianlong with Weichai engine 460

Xinglong h5 automatic transmission tractor Weichai 460 has good horsepower.According to the relevant information, the quality of the Chenglong h5 tractor 460 Weichai 2020 engine is very good.

Natural gas truck, it doesn't matter which brand, it's mainly the engine, choose Weichai for the engine, natural gas engine, Weichai is of better quality, fewer problems, other engines, not recommended.

Tianlong 465 is good. The Tianlong kl465 is equipped with a new D320 platform cab, and adopts a new cab shape design to further reduce wind resistance, which is conducive to saving fuel consumption for vehicles. The four-point airbag shock-absorbing cab is adopted to enhance the driving comfort of the vehicle.

The fuel consumption of Tianlong kl465 automatic transmission tractor is 25 liters to 26 liters. Dongfeng Tianlong KL adopts Dongfeng dci engine, with a displacement of 11 liters and a maximum output power of 465 horsepower, the maximum torque reaches 2200 Nm. After new tuning, it has an ultra-wide economic speed zone of 10001400 rpm. The economic characteristics are more optimized, with high-power turbocharging and air intake.

Big brands are trustworthy. My friend has several models of this model, including 465 and 560, which feel very good.

What is the engine of Dongfeng Tianlong 350 horsepower?

1. The Renault DCI engine adopted by Dongfeng Tianlong, 350 horsepower, maximum power 350 horsepower, and maximum torque of 1600 Nm.

2. Dongfeng Tianlong 350 horsepower front four rear eight fuel consumption 18 oil per 100 kilometers. The fuel consumption of Dongfeng Tianlong 350 heavy vehicle is 18 liters per 100 kilometers. The engine adopts dci's 350 horsepower Guowu model, with a maximum power of 350 horsepower, a maximum torque of 1,600 Nm, and a 5-stage emission standard.

3. The fuel consumption of Dongfeng Tianlong 350 heavy vehicle is 18 liters per 100 kilometers. The engine adopts the 350 horsepower Guowu model of dci, with a maximum power of 350 horsepower and a maximum torque of 1600 Nm. Constant speed fuel consumption refers to the fuel economy indicator when a car is driven at the constant speed on a good road surface.

4. The fuel consumption is 18 liters per 100 kilometers, and the engine adopts dci's 350 horsepower Guowu model, with a maximum power of 350 horsepower and a maximum torque of 1,600 Nm. The gearbox adopts Faster's aluminum-shell gearbox, and the Faster's 12-speed manual transmission carried by the 350-horsepower model, the model is 12JSD160TA, and the highest gear is overspeed.

5. The engine is the heart of the car, which provides power for the car's walking. The car is dynamic, economical and environmentally friendly. Simply put, the engine is an energy conversion mechanism, that is, the thermal energy of gasoline (diesel) is converted into mechanical energy by burning gas in a sealed cylinder, which is the most basic principle of the engine.

What's wrong with the Dongfeng Tianlong Renault engine?

1. Cause analysis: mainly due to incorrect ignition advance angle, low fuel pressure, air intake system leakage, throttle valve position sensor or air flow meter failure, poor operation of fuel injector, poor operation of the EGR system. Troubleshooting steps: After starting the engine, whether the "Check Engine" warning light is off.

2. Analysis of the problem: This problem usually occurs because the rigidity of the car body is insufficient, resulting in deformation of the vehicle while driving, friction or shaking between the door and the frame, or friction between steel plates due to dewelding in some places.

3. There are many reasons for insufficient engine horsepower and weak work, involving the compression state of the crank connecting rod mechanism, whether the valve is tightly closed, the technical state of the lubrication and cooling system, etc., which have a wide range.

4. The air intake system is leaking. In the usage of Dongfeng Tianlong 385 Renault vehicle, I learned that the weakness of this model is caused by air leakage in the air intake system. Users need to repair it. This model is a Dongfeng commercial vehicle.

Dongfeng Tianlong engine idling jitter?

Normal phenomenon.. If after the vehicle starts, we open the hood and see a slight shaking phenomenon in the engine, then this kind of shaking is a steady and regular shaking, which is a normal phenomenon.

The throttle valve is faulty. The above two problems will cause engine shaking and unstable speed. Carbon accumulation will cause insufficient combustion of gasoline, causing the engine to shake.

Solution: Check whether the spark plug has too much carbon and replace the spark plug.

If I don't make a mistake, you must be in the north or in a cold area. Take a look. If the engine is hot, stop and restart. If it still vibrates, then this is a little abnormal. If the car is hot and does not vibrate when it stops and idle, it means that it is because of the cold weather in the morning.
