What Are the Effects of Cold-Weather Starting on Vehicles?
1 Answers
Cold-weather starting affects vehicles in the following ways: 1. The rotational resistance of the engine crankshaft significantly increases as the viscosity of the lubricating oil in the oil pan rises with lower ambient temperatures; 2. The viscosity and density of fuel increase; 3. The high viscosity and poor fluidity of lubricating oil prevent the oil pump from delivering it to friction surfaces in time, leading to dry friction during startup; 4. In cold environments, the wear on various vehicle assemblies is more pronounced. The correct starting method is: 1. After sitting in the driver's seat, press the start button to activate the ACC light, then press it again for a vehicle self-check; 2. Depress the brake and press the one-touch start button to ignite and start the engine. The functions of one-touch start include: 1. Eliminating the need for the original car key or remote to unlock the door; 2. Automatically closing windows when leaving the car; 3. Enhancing safety during night driving; 4. Providing convenient starting and a self-diagnostic protection feature for the original starting system.
