Mercedes Benz 230, 250 and 280, 1968-1972 / 6-Cylinder sohc /

It is the AMG Cylinder Management cylinder shut-off system in particular – completely newly developed by Mercedes-AMG – that significantly improves efficiency: cylinders two, three, five and eight are cut off under partial load, which lowers fuel... The compensating elements are integrated into the cylinder head, and keep the intake and exhaust valves of cylinders two, three, five and eight closed when cylinder shut-off is active. The AMG main menu in the instrument cluster informs the driver whether cylinder shut-off is active, and whether the engine is currently running in four or eight-cylinder mode. Moreover, deciding in favour of a large-displacement, naturally-aspirated eight-cylinder unit with cylinder shut-off resolves the conflict of aims between high output/torque delivery and low fuel consumption figures. This not only enables the load-change losses of the four deactivated cylinders to be reduced, but also increases the efficiency of the four remaining cylinders. 4 litres per 100 km and CO emissions of 195 grams per kilometre (NEDC combined), the naturally-aspirated AMG V8 engine comes in at or below the level of its competitors, however these are unable to match either the output or torque of the SLK 55... The cylinder shut-off function is available over a wide engine speed range from 800 to 3 600 r/min if the driver has selected transmission mode “C” – Controlled Efficiency. This is made possible by intelligent interaction within the highly effective engine management system, with 16 hydraulically compensating elements and a complex oil supply system in the cylinder head.

If another argument comes along we may have to review it. ". Whiting confirmed that if teams feel strongly enough about the Mercedes wing, they are going to have to protest it. As far as the issue of Renault cylinder cutting is concerned, Whiting... It's quite complex but the upshot is, they say it shows that Red Bull are cutting more than four cylinders, which you are not allowed to do. "Actually, the cut pattern is not determined, so you can cut as many cylinders in whatever order you like. We've got the data and we can see quite clearly that there are four cylinders being injected, four cylinders firing and they are timed at the right time, so there's every reason to suppose that there's combustion going on. "Moreover, the throttle... Mercedes motorsport boss Norbert Haug confirmed in Malaysia today that the team had sought clarification from the FIA on the engine issues, while both Red Bull and Renault sought likewise on the subject of the Mercedes wing in Melbourne. Mercedes is understood to be using a hole in the rear wing endplate, revealed when the DRS wing is operated, to duct air through to the front of the car and stall the front wing, reducing drag. The FIA has ruled that Mercedes' controversial DRS-activated 'F-duct' wing is in compliance with the F1 regulations, as is the manner in which Red Bull is cutting cylinders, leading to engine misfiring which has caused suspicion with rival teams.

Hi the MAF that i put on the car that fixed the idle was a borrowed unit,i put my original MAF back on and left the car for 2 days but forgot to turn off the radio which drained the battery. if it is coming up with a MAF fault code & air intake temp (also part of the MAF) then its almost certainly the MAF at fault. Hi i have a 2000 E200 Mercedes,2 Ltr 4 cylinder,it has a surging idle between(NNN) NNN-NNNNpm and it comes and goes during idling (hot & cold). Now you have fitted a good MAF sensor, the ECU still has the adaptation data stored from the bad MAF. the ECU is self learning & adapts itself, when a MAF starts to slowly & progressively give false readings, the ECU adapts to this. with a scan test after it droped the out put signal from the MAF it came up with the codes for-MAF,and AIR INTAKE TEMP SENSOR. after jump starting the car it started and ran good,it idled how it should and it drove good with good throttle response. now the ECU has been reset it cant cope with the incorrect readings from the air mass sensor which is suddenly way out as far as the ECU can see. If fitting the MAF sensor has cured your initial problem, it could be that the adaptation data in the ECU is causing it to run rough now. i tried an air frlow meter from a good running car and it cured the idle but when i go to rev the motor it hesitates and backfires through the intake pipe and revs realy slowly. as a 1st step I would get the vehicle plugged in to a diagonstic tool to reset this adaptation data with a good MAF on.  . Best regards, Paul. we left the car running and whatched the output voltage and after a while it would start to surge in the motor and drop the output voltage signal.

Mike’s team spent many hours welding and checking panel alignment, followed by the full replacement of floor panels (inner and outer), sill panels (inner, outer and jacking points), complete rear-quarter panels, complete rear inner guards, the... The Initial Assessment Once the Mercedes was in New Zealand, Mark carried out some initial disassembly at his home — removing the engine, transmission and some of the interior trim — which revealed the true extent of what would be required to... With the assessment complete, the next step was to hand the Mercedes over to Mike Baucke and his talented team at The Surgery for a complete restoration. Further investigation revealed that Dr Carl Rice of Minneapolis, Minnesota, had originally ordered the car for tourist delivery, collecting it from the factory on December 28, 1966 as a 1967 model year car. Once the body shell was complete then it was time to apply the PPG two-pack epoxy etch primers, high build undercoats and two-pack clear-coat over base-coat to provide a show car finish not only to the exterior of the body, but also under all the... I mention this because at NZCC HQ we’re continually sent a huge amount of emails and letters from enthusiasts all over the country with pictures of their wonderful classic cars, or their project cars in various stages of restoration. The straightening, panel beating and finishing of all the bare steel body work to remove years of minor (and some major) panel damage was meticulously carried out. Thankfully, almost all these chassis and panel parts are available either NOS or as pattern pieces as a result of a very active worldwide Mercedes-Benz restoration market. As with any old car, this Mercedes held a few surprises — both pleasant and unpleasant. Restorative Surgery Once in The Surgery’s workshop, the car was completely disassembled until it was nothing more than a bare shell.
