Mercedes-Benz auxiliary battery works by converting chemical energy into electrical energy to power the vehicle's equipment. If there is an auxiliary battery failure, the following two steps should be taken: 1. First, check the generator's belt and plug to see if there is any looseness, as poor contact caused by looseness can be resolved by tightening; 2. Check if the battery is out of power, and if so, charge the battery. Taking the Mercedes-Benz E-Class as an example: its body dimensions are 5078mm in length, 1860mm in width, and 1484mm in height, with a wheelbase of 3079mm. In terms of power, the Mercedes-Benz E-Class is equipped with a 1.5T turbocharged engine, with a maximum power of 135kW and a maximum power speed of 5800 to 6100 rpm, paired with a 9-speed automatic manual transmission.

Is the OBD Voltage Stabilizer for Fuel Saving in Cars Useful?

Automotive fuel-saving OBD voltage stabilizers are not useful as they cannot modify the core data of the vehicle's ECU. To reprogram a car's ECU, specialized computer programs and experimental models are required for data simulation. OBD fuel-saving devices can only receive and send signals and data but cannot decrypt the manufacturer's encrypted data. The function of an automotive OBD is to monitor the working conditions of the engine's electronic control system, vehicle functional modules, and exhaust treatment system during operation. If a system in the car malfunctions or the exhaust emissions exceed standards, the fault light will trigger an alert. The OBD device can simultaneously monitor multiple systems and components in the car, including: the engine, catalytic converter, particulate filter, oxygen sensor, emission control system, and fuel system.

What does 0w40 mean for engine oil?

0w40 refers to the grade of the engine oil. The number before the 'w' indicates the viscosity of the oil at low temperatures. A smaller number means better fluidity and cold resistance. The number after the 'w' represents the viscosity index of the oil at high temperatures, with a higher number indicating greater viscosity. Engine oil, also known as motor lubricant, serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, dampen shocks, and resist wear. The steps for changing engine oil are: 1. Lift the car, remove the undercover, and place a container of about 10 liters under the drain plug. 2. Unscrew the drain plug and use an air gun to blow into the oil filler for two minutes. 3. After draining, tighten the drain plug and check for leaks with a tissue. 4. Reinstall the undercover, lower the car, and use a funnel to add new oil into the filler port.
