High-speed downhill sliding block linked to N
Some
drivers for fuel-efficient, high-speed
Volvo VIDA DiCE downhill, shift lever position N
block (neutral) glide, which is likely to burn out the transmission. Because
the transmission output shaft speed is high, and the engine idling,
transmission oil pump oil lubrication deterioration, but also for
transmission within the multi-plate clutch, power has been cut off, but
passive piece wheel driven under high-speed operation, easy to cause resonance and slipping due to adverse consequences. The moment is really necessary for a long slope taxiing, keep the shift lever in D sliding block, but not the engine flameout.
D block is still hanging in long-stay parking
Vehicles
equipped with automatic transmission in a traffic jam, some owners are
often only the brake pedal is depressed, the shift lever is maintained
in the D block (road block) does not shift. If the time is very short, it is permitted to do so. However, if parking for a long time the best shift into N block (neutral), and tighten the parking brake. Because
of the shift lever in the D block, automatic transmission vehicles
generally weak forward, slam the brake pedal for a long time, is equal
to the force to stop this forward, so that the gearbox oil temperature,
oil perishable, especially in when the air conditioning system is working, the engine idling more unfavorable.
Kai engine gear mistakenly outside the P or N
Some
drivers in gear to start the engine the P block or outside the N block,
although the engine is not running (because of the
Renault CAN Clip protection of the
chain, only the P and N block to start), but is likely to burn out the
transmission neutral start switch. Neutral start switch is equipped with an automatic transmission. Start
the engine, transmission only in P or N block in order to avoid the
false start of the other gear the car immediately started forward
channeling. Therefore, before you start the engine, be sure to confirm whether the shift lever is in the P or N block.
The throttle can change into high gear
Some
drivers think the D block start, has been to increase the throttle you
can change to high gear, does not know that this approach is wrong. Shift operation should be "closing the throttle upshifts early, step on the gas early downshifts. After
the start of the D block, keep 5% throttle opening, accelerated to 40km
/ h, fast pine throttle, to a gear, then accelerate to 75km / h, loose
throttle can improve a gear. Reduce the speed of vehicles, and a little step on the gas, that is, return to low gear. It
MB Star C3 must be noted, the throttle can not step in the end. Otherwise, we will be forced to hang into low gear, may cause transmission damage.
