Engine monitoring system
The.engines.are.equipped.with.common.rail.system.
and.electronically.controlled.injectors.(D4,.D6).or.unit.
injectors.(D9,.D12,.D16).with.an.electronic.control.
Engine monitoring and the EVC system
unit..
The.injectors.contain.an.electro-magnetic.valve.which.
sets.the.amount.of.fuel.injected.and.the.correct.tim-
ing..The.monitoring.system.measures.the.charge.air.
pressure.and.temperature,.and.calculates.the.avail-
able.air.mass..This.determines.the.maximum.amount.
of.fuel.that.can.be.injected.(smoke.limiter.function).
The.system.also.limits.the.maximum.torque.available.
at.the.engine.speed.registered.to.protect.the.engine.
and.transmission.from.overload.
To.protect.the.engine.at.too.high.coolant.or.charge.air.
temperatures.and.boost.pressure.as.well.as.oil.pres-
sure,.the.monitoring.system.reduces.the.amount.of.
fuel.(reduced.engine.output).until.the.current.values.
are.normalized.
The.engine.monitoring.system.also.has.a.diagnostic.
system,.which.helps.users.and.service.technicians.to.
determine.the.cause.of.any.malfunctions.in.the.sys-
tem.quickly.by.using.the.diagnostic.tool..
Any.fault.is.shown.on.the.EVC.system.tachometer.
display./.EVC.system.display.and.the.VODIA.diag-
nostic.scan.tool..The.diagnostic.tool.has.menus.in.
several.languages.
