Safety valve set pressure, unless otherwise specified by the process, is 1.10 times the normal working pressure, with a minimum of 1.05 times. Function of safety valve: A safety valve is a protective valve whose opening and closing components remain normally closed under external forces. Discharge pressure: For steam safety valves, the discharge pressure should be less than or equal to 1.03 times the opening pressure; for air or other gases, it should be less than or equal to 1.10 times the opening pressure; for water or other liquids, it should be less than or equal to 1.20 times the opening pressure.

What are the causes of engine shaking and the malfunction indicator light coming on?

Engine shaking and the malfunction indicator light coming on can be caused by: 1. Engine carbon deposits: Excessive carbon buildup can intensify shaking, which may be transmitted to the vehicle body, and the engine malfunction light may illuminate; 2. Engine knocking: If low-octane gasoline is used or the engine temperature becomes too high, knocking is highly likely to occur. An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (such as Stirling engines, steam engines), jet engines, and electric motors. The term engine can refer to both the power-generating device and the entire machine including the power unit.

Is the Cruze equipped with a three-cylinder engine?

The Cruze is available with both three-cylinder and four-cylinder engines. The three-cylinder options include a 1.0T L3 turbocharged engine and a 1.3T L3 turbocharged engine, while the four-cylinder variant is a 1.5L L4 naturally aspirated engine. An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (such as Stirling engines and steam engines), jet engines, and electric motors. The Cruze is a vehicle launched by SAIC-GM Chevrolet, featuring classic design elements from the Chevrolet Redline series. It comes with Chevrolet's black bowtie emblems at the front and rear, and incorporates Redline-style design on prominent areas such as the grille, exterior mirrors, wheels, and spoiler.

Should the front and rear tire pressures of a car be the same?

Car front and rear tire pressures should be the same, but a tolerance of 0.1 bar is allowed. Taking a typical family car as an example, the standard tire pressure for the front wheels is usually 2.3 bar when carrying two passengers, and the rear wheels also have a standard tire pressure of 2.3 bar. When the load increases, the tire pressure can be appropriately increased. The front tire pressure can be adjusted to 2.4 bar, and the rear tire pressure can be adjusted to 2.6 bar. Tire pressure refers to the air pressure inside the tire, which is the 'blood pressure' of the car. The level of tire pressure plays a crucial role in the performance and power of the vehicle. Air pressure is the lifeline of the tire; both too high and too low will shorten the tire's service life.

What Causes a Diesel Vehicle to Emit Black Smoke and Lose Power?

Diesel vehicle emitting black smoke and losing power is caused by: 1. Rapid acceleration while driving (usually above 2000 RPM); 2. Cold engine start; 3. Idling (especially noticeable above 2500 RPM); 4. High-altitude effects (commonly seen above 4000 meters altitude). The black smoke emitted by diesel vehicles mainly consists of carbon black particles, which are classified as particulate emissions. Under normal vehicle conditions, this primarily occurs during rapid acceleration and high-idle RPM situations. Solutions for diesel vehicles emitting black smoke: 1. Replace the air filter; 2. Replace the solenoid valve (including the turbocharger's solenoid valve); 3. Replace the fuel filter; 4. Clean the fuel system; 5. Replace damaged components; 6. Add diesel fuel additives.

What problems can an oxygen sensor failure cause?

Problems caused by oxygen sensor failure include: reduced vehicle power, difficulty in acceleration, unstable idle speed during operation, increased fuel consumption, excessive vehicle pollutant emissions, spark plug failure, and fuel supply system failure. When the oxygen sensor fails, the ECU cannot obtain information about the oxygen concentration in the exhaust pipe, and thus cannot provide feedback control on the mixture concentration. In engines equipped with a three-way catalytic converter to reduce exhaust pollution, the oxygen sensor is an essential component. Since the purification ability of the three-way catalyst for CO, HC, and NOx drops sharply once the air-fuel ratio of the mixture deviates from the theoretical air-fuel ratio, an oxygen sensor is installed in the exhaust pipe to detect the oxygen concentration in the exhaust and send a feedback signal to the ECU. The ECU then adjusts the fuel injection volume of the injector to keep the air-fuel ratio of the mixture near the theoretical value.

What Type of Suspension Does the WM EX5 Use?

WM EX5 uses a MacPherson strut independent suspension at the front and a torsion beam non-independent suspension at the rear. The automotive suspension system refers to the entire support system composed of springs and shock absorbers between the body and the tires. The functions of the suspension system include supporting the vehicle body and improving ride comfort, with different suspension setups providing varying driving experiences. The WM EX5 is a compact SUV launched by WM Motor, with dimensions of 4585mm in length, 1835mm in width, and 1672mm in height, and a wheelbase of 2703mm. It is equipped with a pure electric 218-horsepower motor, delivering a maximum power of 160kW, paired with a single-speed transmission for electric vehicles.
