Citroen Triumph shows what causes engine failure?

Sub-engines are also known as Miller cycle engines. It uses a triangular rotor rotational motion to control compression and discharge, as opposed to the linear motion of a conventional piston reciprocating engine. This kind of engine was invented by the German Figarz Wankel, and on the basis of summarizing the research results of his predecessors, he solved some key technical problems and successfully developed the first rotary engine.

Generally, the engine is a reciprocating engine, and the piston does reciprocating linear motion in the cylinder during work, and in order to convert the linear motion of the piston into rotary motion, a crank connecting rod mechanism must be used. Rotary engines, on the other hand, directly convert the combustion expansion force of combustible gas into drive torque. Compared to reciprocating engines, rotary engines eliminate useless linear motion, so that rotary engines of the same power are smaller in size, lighter in weight, and have lower vibration and noise, which has great advantages.

The motion of the rotary engine is characterized by the fact that while the center of the triangular rotor revolves around the center of the output shaft, the triangular rotor itself rotates around its center. When the triangular rotor rotates, the internal ring gear centered on the center of the triangular rotor meshes with the gear centered on the center of the output shaft, and the gear is fixed on the cylinder block without rotating, and the ratio of the number of teeth between the internal ring gear and the gear is 3 to 2. The above motion relationship makes the trajectory of the vertices of the triangular rotor (i.e. the shape of the cylinder wall) resemble a figure of 8.

The triangular rotor divides the cylinder into three independent spaces, each of which completes air intake, compression, work and exhaust successively, the triangular rotor rotates for one week, and the engine ignition does work three times. Due to the above motion relationship, the speed of the output shaft is 3 times the rotation speed of the rotor, which is completely different from the motion relationship between the piston and the crankshaft of a reciprocating engine

Dongfeng Citroen Triumph fault code: There is no response with the ECU of the engine relay unit on the CAN, the computer plug of the engine control unit is loose, resulting in the line breaking, and the data transmission of the communication signal line is abnormal, and the computer plug can be solved by plugging it tightly, and the specific operation steps are as follows:

1. Open the door of the Dongfeng Citroen Triumph cab.

2. Pull the hood switch on the left side of the Dongfeng Citroen Triumph driver's leg.

3. Lift the hood of the engine of Dongfeng Citroen Triumph upwards.

Fourth, use the support rod to support the hood of Dongfeng Citroen Triumph to ensure that the support is firm to avoid danger.

Fifth, plug in the plug of Dongfeng Citroen Triumph computer and it is completed.

Okay? I also encountered the same as you today, hitting the motor does not respond to this fault code.

Sometimes, it is an occasional failure, and the fault code is cleared while looking.

1. The sensor is damaged, the contact is poor, or the signal is interrupted; 2. Poor engine maintenance; 3. The quality of fuel and oil is not good; 4. The combustion of the mixture is insufficient; 5. a spark plug.

malfunction, ignition coil failure; 6. The fuel pump is faulty and the oil circuit is blocked; 7. Blockage of air conditioner filter 1. Sensor problem; The sensors mentioned here include water temperature and crankshaft.

Position, air flow, intake air temperature, oxygen sensors, etc., when these sensors are damaged, poor contact or signal interruption, the ECU of the car cannot accurately obtain engine data, and the engine failure light will be on. 2. Maintenance problems; Poor engine maintenance is the most common cause of engine failure to light up. We know that the vehicle has a certain maintenance cycle, if the owner does not maintain on time, coupled with bad driving habits, then it will increase the burden of engine operation, and finally can only remind you through the fault light to care about your car 3, oil quality problems; The oil quality here includes fuel and engine oil, we know that the fuel filled by the car is generally marked, and the engine oil is also semi-synthetic and fully synthetic, the manufacturer will generally recommend the owner to use which grade of fuel, which type of engine oil, if the owner does not add as required, it will cause wear and tear of the engine in the long run, and the fault light is not to blame.

Poor combustion of the mixture; The failure of the spark plug, ignition coil, fuel pump, and oil circuit blockage of the engine will cause poor combustion of the rubber engine mixture. Poor combustion of the mixture is caused by the problem of engine carbon deposition or knocking, and these will eventually be detected by the engine's oxygen sensor and reported to the ECU, which will naturally turn on the fault light to warn of the intake air intake problem; When the engine burns, it needs to take in the air, and in the process the air cleaner is required.

It is very important, if the air filter of the car is not clean, it will affect the air intake of the car if it is not cleaned regularly, and it will be blocked in the long run, and in serious cases, it will cause the engine failure light to turn on. pressurization issues; Intake booster lines, turbochargers.

It will also cause the engine failure light to illuminate. The most common of these is turbocharger damage, while the vehicle can also experience symptoms such as oil leakage, high oil consumption, loss of power, metal noise, and blue or black smoke from the exhaust pipe. 7. Exhaust problems; Rear oxygen sensor, three-way catalytic converter.

Exhaust camshafts and bearings.

The most common of these is a failure of the three-way catalytic converter that causes the engine failure light to illuminate. The use of leaded gasoline for the defense cover, the use of lead or silicon lubricating oil additives, the bump of the three-way catalytic converter, and the failure of the engine oil supply system are some of the factors that can easily cause the failure of the three-way catalytic converter. anti-theft system; If the car's electronic immobilizer fails, or if the immobilizer does not match the engine electronic controller, the immobilizer system will also cause the engine to not work properly and the engine fault light will be lit at the same time.

Summary. What's going on with the 07 Citroen Triumph not starting well? With him as follows.

Carbon deposits can cause insufficient combustion of gasoline and cause the engine to shake. The impact of engine carbon deposition on the car is quite large, first of all, to reduce the engine power, that is, to make the power output uneven and gradually decay, in other words, more and more powerless. The second is to increase fuel consumption and increase your financial burden.

The third is the difficulty of cold start, that is, the difficulty of ignition, it is not easy to get on the car, and finally the carbon deposit in the combustion chamber is strict, and a heavy one will also cause cylinder detonation, and there will be a sound of low-speed acceleration, which will cause damage to the piston and crankshaft, and cause high temperature of the engine, which will seriously affect the safety of the car. Then there are the exceedances of emissions. Happy New Year!

Hold on. What's going on with the 07 Citroen Triumph not starting well? With him as follows.

Carbon deposition will cause insufficient combustion of gasoline, which will cause the engine to shake and play in a strange state. The impact of engine carbon deposition on the car is quite large, first of all, to reduce the engine power, that is, to make the power output uneven and gradually decay, in other words, more and more powerless. The second is to increase fuel consumption and increase your financial burden.
