ProVent® – Protects the crankcase and theenvironment

The service life of dieselengines used in commercialand industrial applicationsis longer than the servicelife of diesel engines usedin motor cars. Thereforecomponents of dieselengines used in industrialapplications are subject tohigher requirements withregard to efficiency andlifetime. One of thesecomponents is the closedcrankcase ventilationsystem, which is becomingincreasingly important.

Generation of blow-bygases

For every piston stroke in acombustion engine there areexhaust gases which flowbetween the piston rings andsleeves. These gases enterthe crankcase. In turbochar-ged engine applications, aircan also make its way intothe crankcase through theoil return pipe of the turbo-

charger. These gases aregenerally called blow-bygases. The pressure theygenerate leads to an unac-ceptable pressure build-upand crankcase ventilationbecomes necessary.

In many countries, regulati-ons governing car emissions

stipulate that gases removedfrom the crankcase duringthe ventilation process mustnot enter the atmosphere.That is the reason why blow-by gases from car enginesare redirected by so-calledclosed crankcase ventilationto the intake pipe assemblyand burned. Commercial and

industrial diesel engines arealso subject to internationalemission regulations whichin future can only be metthrough the application ofreliable closed crankcaseventilation systems.

Closed crankcaseventilation

All MANN+HUMMEL crank-case ventilation solutions aresuitable for use in closedsystems. They thereforeoffer ideal protection forthe crankcase and enablecompliance with futureenvironmental regulations.Contaminants can causedamaging, oily deposits in

the engine intake, turbochar-ger and charge cooler. Inaddition, they compromiseengine performance, increasefuel consumption and shor-ten engine life. To avoid this,an oil separator (9) is usedto remove oil from the blow-by gas. The separated engi-ne oil is then returned to the

oil sump without loss whereit can re-enter the oil circuit.After the blow-by gases arecleaned in the oil separator,they pass the pressure valve(4). This valve regulates thepressure inside the crank-case to within permissiblelimits.

Open crankcaseventilation

All ProVent® systems canalso be used for open crank-case ventilation. In this casethe pressure regulator of theProVent® is not in operation.The outlet port (2) leads tothe atmosphere. In this con-figuration there is a slightexcess pressure in the crank-case.

Safety valve

A safety valve (item 6 indiagram) is integrated in thehousing cover to protect theengine from an impermissi-ble rise in pressure in caseother components fail. If theengine is fitted with a crank-case pressure monitoring

Oil separator

The filter elements used byMANN+HUMMEL (see item2 in diagram) are the resultof intensive developmentwork and experience. Therespective medium is perfec-tly matched to each ProVent®

while satisfying the require-ments for quality and eco-nomy. The high performancecoalescence separators areable to reduce the residualoil content of the blow by gasto an extremely low level.Depending on the particlespectrum of the oil content,the separator uses the mostappropriate separation prin-ciple. As a result, ProVent®

is ideally suitable to compre-hensively meet the require-

ments of the next generationof engines. Servicing of theoil separator is made accor-ding to the installation andmaintenance instructionsunder consideration of thespecifications of the engineproducer.

Pressure regulation

In closed systems the pres-sure regulator (item 3 in dia-gram) can be set as requiredto maintain a constant levelindependent of the negativepressure of the air intakemanifold. The set pressurelevel simply depends on thequantity of blow-by gases(see Fig. 3).The crankcase pressureremains within a narrow

ProVent® performance

Fractional separationefficiency

As there is no standard go-verning the determinationof separation efficiency, itis not possible to publishstandardised values.However, numerous testshave shown that operatingconditions such as speed,output, torque and age ofthe unit are relevant factorswith regard to the generationof oil droplets. Thus the sizeand distribution of the oildroplets partly depend onthese factors.

The separation efficiencieslisted in the table forMANN+HUMMEL HE andUE media relate to an oilpresence of≤ 1 g/m³ in the blow-by gaswith an oil droplet distributionof ds = 0.8 (Sauter diameter).

In respect of the Δp value, alower value signifies a greaterflexibility with regard to themounting location. If the Δpis lower, the ProVent® can befitted closer to the oil level orcheck valve in the oil returnpipe of the engine.

The exact fractional separati-on efficiencies, i.e. the sepa-ration efficiencies of certainparticle size ranges, have tobe determined for the res-pective application in tests.

The non-existence of astandard and numerousoperating parametersrequiring definition meanthat in many cases dimen-sioning of the filter isnecessary.

In this case MANN+HUMMELoffers support and technicalassistance.

Instructions regarding the use of ProVent®

Mounting location on theengine

ProVent® systems are desi-gned for OE producers andare also suitable for retrofit-ting.

Instructions

• ProVent® can be fitted tothe engine or applicationframe.

• Observe the installationand maintenance instruc-tions of the respectiveProVent® system.

Connection to the engine

Observe the following whenconnecting to diesel engines:

• Position the blow-by outletin an area free of splashingoil (e.g. upper area of thecrankcase).

• Observe the mounting andmaintenance instructionsof the respective ProVent®

system.

Connection with a closedsystem

The respective outlet port isconnected to the engine in-take. As opposed to conven-tional systems, the ProVent®

installation location is prac-tically independent of thenegative air intake pressureon the outlet port. The resultis a large degree of flexibilityfor the fitting position on theengine. The negative air in-take pressure present during

operation sucks the blow-bygas via ProVent® and returnsthe cleaned blow-by gas tothe engine air intake.

Connection with an opensystem

The blow-by gas now freeof oil is released into theatmosphere.

Oil return

The respective port of the oilreturn (see diagram on page15) is connected to the oilsump via a drainage pipe.There are two principalconnection possibilities:

1. Below the oil level

The oil return is connectedvia a drainage pipe belowthe minimum permissible oillevel of the engine oil sump.According to the principle ofconnected pipes, the sameoil level is present in the oilsump and the drainage pipe.This oil receiver acts like asiphon so that when the oilis sucked from the outlet portthe blow-by is directed viathe oil separator. The negati-ve pressure in the oil returnpipe during operation is thesame as the negative pres-sure at the oil separator. Asopposed to conventionalsolutions, this intake negati-ve pressure is reduced dueto design considerations so

that the height of the oilcolumn in the drainage pipeduring operation is accor-dingly low. As a result thedrainage pipe need only takeinto account a respectivelylow oil column and this ena-bles numerous installationpossibilities.

2. Above the oil level

This connection variationrequires fitting of a checkvalve which is available asan option. The valve is fittedin the drainage pipe as closeto the engine as possible.Separated oil collects abovethe check valve during ope-ration. The check valve is

closed during operation bythe negative suction pressu-re present in the housingof the ProVent®. When theweight of the oil column isabove the closing pressureof the valve, for examplewhen the engine has beenswitched off, the separatedoil flows back to the oilsump.

Instruction

In all cases observe Fig. 2on page 15, the generaloverview, and the respec-tive installation and main-tenance instructions.
