What happens when the engine of Dongfeng commercial vehicle Renault starts after starting and wants to turn off?

1. The combustible mixture is too thick. The remaining part that has not been burned will accumulate and be carbonized on the spark plug electrode, causing the spark plug to jump abnormally until the carbon is damaged. The reasons why the combustible mixture is too thick are generally that the oil plane of the carburetor is too high, the main air volume hole of the carburetor is blocked, and the air filter element is seriously blocked.

2. The main reason why the engine shuts down is that the operating load torque (torque) of the car is greater than the torque output by the engine, whether in driving or starting.

3. There is a fault in the car ignition. Due to the poor contact of the car's ignition switch, the car's ignition system will fail. Solution: Replace the ignition switch. There is an abnormality in the fuel injector and fuel filter.

Dongfeng Tianlong 465 Longqing engine and 465 Renault launched that fuel-saving one

Renault. Dongfeng Tianlong mainly uses Cummins engines and Renault DCI engines, especially Renault DCI engines, which are very fuel-efficient, powerful and reliable in quality.

Dongfeng Tianqing 465 tractor Guoliu starts better. However, Renault machines are domestic machines without foreign technology at all. Dongfeng manufacturers are issued by themselves. Dongfeng manufacturers sell vehicles at the bottom price. After 2-3 years, the maintenance cost is high.During driving, the engine speed of a general electric injection vehicle is about 2200-2500, which is the most fuel-efficient.

Good. Save fuel. Dongfeng Tianlong kl465 Renault engine will have certain fuel economy advantages in high-speed logistics scenarios. Configuration. The Dongfeng Tianlong kl465 Renault engine meets the national six emission standards, with a displacement of 8L and a maximum power of 465 horsepower (343kW).

Therefore, in terms of power, economy and reliability, 465 Longqing is better than 465 Renault. In the process of burning oil, carbon accumulation will inevitably occur. If there is too much carbon accumulation, there will be abnormal phenomena such as difficulty in starting, unstable idling, poor acceleration, urgent refueling, exhaust gas exceeding the standard, and increased fuel consumption.

How to deal with the fault of Dongfeng Tianlong Renault engine intake preheating control short circuit to the ground?

1. When the temperature is too high, you can touch it with your hand, and it can be judged that the size cycle conversion of the thermoster is abnormal. If there is air in the cooling system, it will form air resistance, causing poor cooling water circulation, resulting in excessive engine temperature.

2. The preheating plug of the engine has been burned out because the resistance value is too small. Just find the heating element and unplug the harness plug. The preheater is to use the flue gas in the tail flue of the boiler to preheat the air entering the boiler to a certain temperature through the internal heat sink. It is used to improve the heat exchange performance of the boiler and reduce energy consumption.

3. If the heating plug itself is short-circuited, just replace it with a new one. If the line is short-circuited, find the short-circuit point along the line, and change the line or insulate it.The fuse may have been burned and should be taken into consideration during inspection.

4. The reason why the engine preheating plug burns out is that the resistance value is too small. Find the heating element and unplug the harness plug. The preheater uses the flue gas in the flue at the tail of the boiler to preheat the air, and then enters the heated surface of the boiler through the internal radiator. It is used to improve the heat exchange performance of the boiler and reduce energy consumption.

5. Either the relay is broken or the wire is not connected. My major is the third country.

6. The gap between the crankshaft and the large and small tiles exceeds the standard, resulting in oil leakage and low oil pressure. Solution: Overhaul. The spring of the pressure limiting valve or pressure relief valve is too soft or the hair jam or the steel ball is damaged, causing the function of the valve to disappear or weaken, resulting in a decrease in oil pressure. Solution: Replacement and maintenance.

Is the Renault Fenglang engine the same as Nissan? What engine does Dongfeng Renault use

Ray The engine of Noo Fenglang is Nissan. Renault Fenglang uses a 0-liter naturally aspirated engine, which is the same origin as Nissan's MR series engine and is manufactured by Nissan technology.

the same.If you check Autohome, you can know that 13 Renault Fenglang engines are produced by Nissan, which is the same as Nissan. The key layout of the 2013 Fenglang console has been slightly adjusted. In terms of configuration, the new car has added USB interface, Bluetooth, R-Link multimedia system and other configurations.

According to the official introduction of Renault Motors, Renault Fenglang uses a 0-liter naturally aspirated engine with a maximum horsepower of 137 horsepower, a maximum power of 101kw and a maximum torque of 191N·m. The naturally aspirated engine is the most traditional engine. It has a low manufacturing cost and a relatively simple process, so the failure rate is relatively low.

What engine does Renault Fenglang use? According to the official introduction of Renault Automobile, Renault Langfeng adopts a 0-liter naturally aspirated engine with a maximum horsepower of 137 horsepower, maximum power 101kw, maximum torque 191N·m naturally aspirated engine is the most traditional engine, with low manufacturing cost and relatively simple process, so the failure rate is relatively low.

In terms of power, Renault is equipped with a 0-liter naturally aspirated engine with a maximum horsepower of 137 horsepower, a maximum power of 101kw and a maximum torque of 191N·m. In terms of gearbox, the entire series of Renault Fenglang uses a CVT stepless transmission.

What's wrong with the black smoke from the Dongfeng Tianlong Renault engine?

Another reason is that the cylinder pad of the water-cooled engine is broken, and cold water enters the cylinder. If there is no leakage, the water in the water tankIf the consumption is too fast and the exhaust pipe is slightly white, the cylinder pad should be replaced for this reason.

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

The reasons for the black smoke from the exhaust pipe of the car's rapid acceleration are as follows: it may be caused by the pressure of the car's cylinder is too low, resulting in incomplete combustion.

The Dongfeng Tianlong Renault engine has black smoke. If it's a new car, it's better to run more. If it is a car that has been driven for a long time, the brake disc and brake pad may be rusty. Just remove it and grind off the rust layer with sandpaper;Or the brake pads are seriously worn, so you need to replace them.

The Dongfeng Tianlong Renault engine is normal when there is a loud cylinder knocking sound and the throttle is normal. What is the reason?

1. Excessive carbon accumulation of the engine: Excessive carbon accumulation of the engine in the combustion chamber will not only increase the compression ratio (generate high pressure), but also produce high-temperature hot spots on the carbon accumulation surface, causing the engine to explode.

2. The oil surface is too low or the oil filter and oil channel are blocked by foreign matter, and the performance of the oil pump is degraded or damaged. The noise is caused by the damage of the crankshaft connecting rod and the large and small shaft tiles due to insufficient lubrication, and the engine needs to be overhauled.

3. Abnormal sound of Dongfeng Tianlong Renault engine: the wear of the piston, the knocking sound caused by the excessive gap between the piston and the cylinder wall.The sound of the engine bursting and knocking on steel. It may be a valve failure. Please take care of your car.

4. Check or follow up your air filter, and your supercharger, especially your supercharger, to see if there is oil in the air intake pipe of the air conditioner or the inlet pipe of the in-cooler? If there is, you need to replace the supercharger. If there is no sweeping, you can change the supercharger core.

5. Analysis of the specific reasons for the loud engine noise: 1. When you step on the accelerator, you will find that the acceleration is not obvious, there is a lack of power, and the engine has a hysterical sound. The most likely time to happen is when the engine is hot, or cold, or when there is a shortage of oil.
