How to Determine if a Car's Oil-Gas Separator is Faulty?

If a car's engine experiences shaking after cold starts, burning engine oil, or the engine fault light comes on due to an overly rich air-fuel mixture, it can be determined that the car's oil-gas separator is faulty. It is recommended to promptly visit a 4S shop for inspection to avoid affecting driving safety. Relevant information about the oil-gas separator is as follows: Introduction: The oil-gas separator is a device that separates crude oil and associated natural gas produced from oil wells. The oil-gas separator is placed between the submersible centrifugal pump and the protector, separating free gas from the well fluid. The liquid is sent to the submersible centrifugal pump, while the gas is released into the annular space between the tubing and casing. Function: The oil-gas separator is one of the important components of the entire submersible electric pump system. Its primary function is to serve as the suction inlet for oil and gas entering the multi-stage centrifugal pump. Secondly, before the gas-liquid mixture enters the multi-stage centrifugal pump, the separator removes free gas from the well fluid, thereby reducing the impact of gas on the working characteristics of the submersible electric pump, preventing cavitation and gas lock in the centrifugal pump, and ensuring the normal operation of the multi-stage centrifugal pump.

How to Drive a Manual Transmission Car for Better Fuel Efficiency?

When going uphill, the engine traction force Fe=Fz+F31, and the car maintains a constant speed; when Fe＞Fz+F31, the car accelerates, and the engine requires fuel to do work. As long as you don't stomp on the gas or brakes aggressively, the fuel consumption difference is minimal. Therefore, for cars equipped with cruise control, enabling it on good roads with light traffic to maintain Fe=Fz+F31 and keep the car moving at a constant speed can slightly improve fuel efficiency, though the effect is not significant. On flat roads, F31=0, and Fe=Fz, the car maintains a constant speed; when Fe＞Fz, the car accelerates, and the engine requires fuel to do work. Similarly, using cruise control to maintain Fe=Fz and keep the car moving at a constant speed can slightly improve fuel efficiency, though the effect is not significant. (Note: On flat roads, many taxi drivers aggressively step on the gas and then coast in neutral. Long-term observations show that fuel consumption decreases noticeably at lower speeds. However, this method can lead to loss of control at higher speeds and is not recommended.) When going downhill, Fe+F31=Fz, and the car maintains a constant speed; when Fe+F31＞Fz, the car accelerates. When F31≥Fz, the engine doesn't require any fuel to do work, and the car can move forward.

Are OEM Wheels Cast or Forged?

OEM wheels are cast. Below is an introduction to the ET value related to wheels: 1. Meaning: The ET value of a wheel refers to the offset between the mounting surface and the centerline of the wheel rim, simply called the offset. The J value represents the shape and height of the wheel flange. 2. Introduction to ET value types: A zero-offset wheel means the mounting surface of the wheel is located at the centerline of the wheel; a positive-offset wheel indicates the distance between the mounting surface and the wheel center is towards the outer side; a negative-offset wheel means the distance between the mounting surface and the wheel center is towards the inner side.
