Распознанный текст таблицы — требует сверки с оригиналом
| Item | Symptom | |
|---|---|---|
| Wontt start (no initial combustion) | The starter is used to crank the engine, but there is no combustion within the cylinders, and the engine wontt start: | |
| I | Starting problem (initial combustion; then stall) | There is combustion within the cylinders, but then the engine soon stalls |
| (Starting takes a long time ) | Engine won't start quickly- | |
| 1 | Idling instability (Rough idling) | Engine speed doesn't remain constant; changes during idling Usually, a judgement can be based upon the movement of the tachometer point- er, and the vibration transmitted to the steering wheel, shift lever; body, etc. This is called rough idling: |
| Incorrect idling speed | The engine doesn't idle at the usual correct speed, | |
| 8 | Improper idling continuity Die out Pass out | This non-continuity of idling includes the following elements_ The engine stalls when the foot is taken from the accelerator (1) Die out_ pedal, regardless of whether the vehicle is moving or not: The engine stalls when the accelerator pedal is depressed or (2) Pass out being while it is used |
| Hesitation Sag | Hesitation "Hesitation" is the delay in response of Normal the vehicle speed (engine rlmin) that occurs when the accelerator is depressed in order to accelerate from 8 Initial the speed at which the vehicle is now accelerator gieaporany drop in vehi- traveling; or a pedal 1 cle speed (engine during such depression acceleration: Serious hesitation is 'Sag called "sag" | |
| Time IFU0223 | ||
| Poor acceleration | Poor acceleration is inability to obtain an acceleration corresponding to the or the inability to degree of throttle opening, even though acceleration is smooth, reach maximum speed: | |
| 1 | Stumble | Engine rlmin response is delayed when the accelerator pedal is initially depressed for acceleration from the stopped condition: Normal 8 Initial accelerator 1 pedal depression Stumble Idling |
| Time IFUozz4 | ||
| Shock | The feeling of a comparatively large impact or vibration when the engine is accelerated or decelerated. | |
| Surge | This is repeated surging ahead during constant speed travel or during variable speed travel | |
| Knocking | sharp sound like a hammer striking the cylinder walls during driving which and adversely affects driving: | |
| 1 | Run-on (Dieseling) | The engine continues to run even after the switch is turned OFF. This is called dieseling |
