7.1. It is sometimes rational to spend visual survey of system of injection
From time to time check the laid hoses and their connections on correct landing and presence of cracks of weariness:
- Vacuum hose to the gauge of absolute pressure.
- Vacuum hose of the brake amplifier.
- Whether all hoses of ventilation of the engine in a good condition? Or they are corked, polluted or made oily?
- Whether are tight топливопроводы?
- Whether connections and a pressure regulator are tight, and also...
- ... The drain pipeline from a pressure regulator? Pay attention to cracks and not tight connections.
- If during works under an engine cowl it is necessary to "extend" for the wire tip, it is possible after that to provoke contact easing. For preventive maintenance process conclusions a contact spray. In «serious cases» it is possible to bend contact uvulas "sensitively".
Additional air – instal uncertainty in work РСМ
Leaky places in system всасывания lead to occurrence of uncontrollable additional air. It instal uncertainty in РСМ and leads to incorrect results, for example, at preparation топливовоздушной to a gas mixture: atomizers deliver to the engine not enough fuel. A consequence: the gas mixture неконтролируемо is impoverished.« Poor »engines in a range of partial loadings have propensity to« pauperisation jerks »gas mixture and at full loading it is possible to hear besides« detonation knocks ». The described symptoms are among other and« external lacks »: in due course they can lead to more expensive consequences (for example, the burnt down bottoms of pistons, teases of the piston, defects of valves) and so forth). To protect from all it the Mondeo, the block of cylinders of engines Duratec"supervises"the gauge of detonation combustion. As soon as noise become"unhealthy", the gauge informs on it in РСМ. The block of management of transmission establishes "the detonation" cylinder further for the late moment of ignition. Attentive drivers mark this intervention: Mondeo reacts much more хладнокровней to pressing of a pedal of gas. That the detonation gauge has appeared"unemployed", it is necessary to examine inlet system more often.
