The pressure difference of the exhaust pipe of the national five car transmits a large pressure diff

The exhaust pipe is generally divided into three sections, the head section is the so-called exhaust manifold, there are two forms 4-1, 4-2-1, the front is to focus on the design of high rotation power, the latter is to focus on the design of low rotation torque, and the exhaust head section is of equal length, this design is to prevent the exhaust pulse between the exhaust pipes, mutual interference to produce exhaust turbulence, directly affect the power output of the engine This is cast iron, or aluminum alloy, so it is not so easy to damage, you can use it with confidence

The middle section has no practical significance, and the purpose is to divert the flow.

In the rear section, there are also two types of in-line type and backpressure type, the former focuses on high-rotation output, and the latter focuses on low-rotation torque. The exhaust business is also slightly different, with the former being more expensive and the latter being deep and powerful. The diameter of the exhaust at the end of the tail section is 15%-20% of the original factory for the best lifting principle.

If it is a turbo modification, it is necessary to choose a wider middle and tail section, and match it in a way that is gradually amplified, the purpose is to gradually amplify the exhaust pulse, which is smoother and will not produce turbulence The exhaust pipe is large, and the car has great power, but it is not that the exhaust pipe can run fast, because of environmental protection, some large displacement cars due to exhaust gas treatment, add two more groups, and some look at the four exhaust outlets, in fact, it is also an exhaust pipe with two outlets. There is also the V-engine, which works by two exhaust pipes due to the large displacement of eight or ten cylinders. But there is no direct connection with power, more about environmental protection.

What you said at the bottom is incorrect. There is no car in the world that has been designed with one cylinder and one exhaust pipe. Because the cylinder work is not at the same time, there is a sequence, as long as there are no more than twelve cylinders, there is no two cylinders at the same time in the exhaust, so there will be no back pressure, then an exhaust pipe connected to four cylinders or five cylinders will not affect each other.

Differential pressure sensors are basically for diesel engine aftertreatment systems! The main function is to monitor the pressure difference between the front and rear of the exhaust pipe DPF, if the pressure difference between the front and rear is large, it means that the DPF is blocked, give the signal PCM, and let the PCM control the regeneration DPF

Summary. Hello, a broken exhaust differential pressure sensor has an impact on the car: a broken differential pressure sensor in the exhaust pipe will cause the fault light to illuminate and the car computer will limit the engine torque.

In addition, if the differential pressure sensor is broken, the signal collected by the engine control unit will be incorrect, and the wrong signal will make the calculated air intake inaccurate, resulting in the engine not working properly. A differential pressure sensor is a sensor used to measure the difference between two pressures, usually at the front and back of a piece of equipment or component. The sensor is a detection device that can feel the measured information, and can convert the felt information into an electrical signal or other required form of information output according to a certain law to meet the transmission details of the information.

Hello, a broken exhaust differential pressure sensor has an impact on the car: a broken differential pressure sensor in the exhaust pipe will cause the fault light to illuminate and the car computer will limit the engine torque. In addition, if the differential pressure sensor is bad, the signal collected by the engine control unit will be incorrect, and the signal error will make the calculated air intake inaccurate, resulting in the abnormal operation of the Duanchang sock engine.

A differential pressure sensor is a sensor used to measure the difference between two pressures, usually at the front and back of a piece of equipment or component. The sensor is a kind of detection device, which can feel the measured information, and can transform the felt information into an electrical signal or its information output in the form of rapid and other needs according to a certain law, so as to meet the transmission details of the information.

A differential pressure sensor is a sensor used to measure the difference between the pressures of two ready pins, usually used to measure the pressure difference between the front and back ends of a device or component. The sensor is a kind of detection device, which can feel the measured information, and can transform the felt information into an electrical signal or other required form of information output according to a certain law, so as to meet the requirements of information transmission, processing, storage, display, recording and control.

What are the worst-case consequences?

I'm in a hurry to run more than 300 kilometers at high speed, does it affect?

That will definitely affect it, and it is recommended that you fix it before getting on the highway, in case something happens on the highway.

A broken differential pressure sensor in the exhaust pipe will cause the fault light to come on, and the car computer will limit the engine torque. In addition, if the differential pressure sensor is broken, the signal collected by the engine control single slip section element will be wrong, and the signal error will make the calculation of Chunxian's air intake inaccurate and cause the engine to work abnormally.
