Bore and stroke is 83.2 mm × 73.5 mm (3.28 in × 2.89 in). The big advantage of the emissions engine is that it can run lower octane (91) petrol. Unlike the other 560 engines, the emissions version never had the compression ratio revisions. The 2.65 contrasts with the 2.24 ratio used on the 500, and the 2.47 used on the 420. The move to the 560 allowed power to be raised to 178-180kW depending on market. To meet the E32’s specs a high output version of the 560 engine was offered with 220kW. The W140 was apparently delayed to respond with a V12 and the 560 was a short term competitive response.
A Cat will normally make a rattling sound if its all blocked up inside. BenzWorld.org forum is one of the largest Mercedes-Benz owner websites offering the most comprehensive collection of Mercedes-Benz information anywhere in the world. To be honest, it is not because MB cars are weak in this area, but because most owners forget that spark plugs are wear items and need to be replaced at the , The E26 is a 2.6 L (2,597 cc) version. I am inclined to trust the technical data book and spec sheet.
The 560 offers more power than the 500, although the 500 has the reputation of being the smoother engine. , The E 32 ML is a special version of the 3.2 L (3,199 cc), fitted with a helical Twin-screw type supercharger and water-to-air intercooler. The CAFE regulations imposed fines on manufacturers based on the average fuel consumption of their entire range.

If these parts fail, it is not economically viable to fix the engine. However, the official spec sheet that was included for the Australian versions lists it as 182kW and with 400Nm of torque, as does the 1987 technical data book. The high output motors also have a different fuel distributor, same as the the early R129 500SL. All 10:1 compression engines have high compression pistons. (I notice a really (really really) annoying tick from the exhaust/engine from 1500-2500RPM), could the cat be blocking the engine exhaust gases and causing the tick? Qualification for membership is for owners of such cars and true enthusiasm for the marque. AustralianCar.Reviews has over 1,550 extensive reviews of 62,000 Australian cars... A new crankshaft with bearings adapted to the high torque; A temperature-resistant coating for the pistons to withstand peak This version of the 560 was equipped with a 2.47:1 rear end instead of the 2.65 used in other 560s. This was also the exhaust used for the Australian version. No known issues with the chain; the balancer issues are on the M272. The Mercedes-Benz M113 (and similar M155) engine is a gasoline-fueled, spark-ignition internal-combustion V8 automobile engine family used in the 2000s. A diagram ofthe belt path is provided below. All have forged steel connecting rods, a one-piece cast camshaft, iron-coated aluminum pistons and a magnesium intake manifold. A dual-length Variable Length Intake Manifold is fitted to optimise engine flexibility. The exhaust is less restrictive for one in the Australian version. Article updated based on the spec sheets Trent sent. When catalysts were fitted, there were two. The Daimler Group are the proprietors of the Community Trademarks "Mercedes", "Mercedes-Benz" and the three pointed star logo. It has fracture-split forged steel connecting rods. Even the emissions versions have plenty of power and are a delight to drive. This is the same Mercedes C-Class W202 Workshop Manual used by Main Dealer Garages. The electronic parts catalogue makes no mention of the 182kW output, but the official tehcnical data literature from Mercedes-Benz does. To deal with the vibration problems of a 90 degree V6, a balancer shaft was installed in the engine block between the cylinder banks. Recommend that this job be performed on a cold engine! The new 112-series includes the following engines: E24 M112, M112 E26, E28 M112, M112 E32 ML, and M112 E37.
Mercedes offered two versions for this case. Complete Serpentine (Poly-V Belt) Replacement DIY M112 & M113 Engines 1) Here's a picture ofthe three parts that will be replaced. The M117 is a longer stroke version of the M116. This website is not in any way connected or affiliated with the Daimler Group. There is a power output difference between the strict emissions variant (e.g USA) which has a 178kW rating and the lighter emissions variant (e.g Australia) which has a 182kW rating. Bore and stroke is 89.9 mm × 68.2 mm (3.54 in × 2.69 in). Because of these changes, these engines produced greater power with reduced noise and emissions compared to the preceding M112 and M113. While not the subject of this article, the compression ratio changes were also applied to the 420 and 500 engines, providing a useful power boost. These engines evolved over time with the final iteration coming between 1985 and 1991. Membership is extended to non-owners with a genuine interest in the best engineered car in the world. The larger motor still allowed good performance even when de-tuned for idle emissions. The compression ratio is 10.0:1. The Mercedes-Benz M112 engine is a gasoline-fueled, 4-stroke, spark-ignition, internal-combustion automobile piston V6 engine family used in the 2000s. Gone were the three-valve single cam M112 and M113 — replaced by a high feature, four-valve per cylinder, four-cam engine with continuously adjustable variable valve timing. Both of these versions ran the standard 9:1 compression.
No known issues with the chain; the balancer issues are on the M272.
It was the same story with the M116 420. The revised KAT version now made 205KW, a useful improvement. At the same time larger valves were also specified.
But they are designed to be maintained: they're simple cars, easy to work on, with well-designed fixings and attachments. The ECE (Code 822) versions carried the following sticker on the radiator support: High output engines have different camshafts with ECE, RUF and KAT camshafts all having different part numbers. The site includes MB Forums, News, Galleries, Publications, Classifieds, Events and much more! Discussion in 'Engine, Drivetrain, Fuel and Exhaust' started by flyingtech55, Mar 25, 2014. These improvements were not made to the engines for very strict markets such as Australia, the USA and Japan. The crossover pipe and single catalyst can clearly be seen.
Transmission: 5/6-speed manual 4/5-speed automatic . This made the ECE version redundant, as the RUF version now made 220KW. I have read that the high output engines had a reinforced transmission, but have not seen any factory evidence so far. The ECE and RUF cams have the same profile. W123s, W124s etc. It was this emissions engine that was the only 560 available in the R107. What an informative post, I never really know that the Australia have a restrictive emission regulation similar to USA, Japan and Switzerland. Save my name, email, and website in this browser for the next time I comment. My 1988 and 1989 560SECs were both this version. Wrong oil/filter/intervals can cause some problems with sludge and worn slide rails, but those are both fairly rare.
https://en.wikipedia.org/wiki/Mercedes-Benz_SL-Class, (You must log in or sign up to reply here. Mercedes still faced a challenge against the E32. RUF are 24/25 and USA is 26/27. Therefore, from 9/87 the RUF and KAT versions were revised. There is some confusion over the exact power ratings of these emissions engines. I have an ’87 ECE 560, bought it last year, in good condition but improving bits as I make time, Quick question to anyone in the know, my ECE engine with Tri-Y headers have a catalytic convertor on it, I know it shouldn’t and am intending to take it up once garages open up again (Corvid 19 lockdown in Ireland), What would be the symptoms of a cat on the exhaust? The Mercedes-Benz M112 engine is a gasoline-fueled, 4-stroke, spark-ignition, internal-combustion automobile piston V6 engine family used in the 2000s. The high output models have a separate oil cooler and pump.
The 2.65 contrasts with the 2.24 ratio used on the 500, and the 2.47 used on the 420.
The primary destination of this 560 was the USA, but it also formed the basis of the Australian and Japanese versions, with minor changes. Awesome...so what should I expect to look for at 100k you think? The 560 gives great power even in the emissions compliant version made available to Australia and the USA. (the picture […], […] many enthusiasts seek out the higher power imported 420, 500 and 560SEC models, especially the later ones with 10:1 compression. The RUF version could still be retrofitted with a catalyst.
). Introduced in 1998, it was the first V6 engine ever built by Mercedes. (which had a 70 pr cent higher output); Harder valve springs to increase the rated engine speed (from 6000
I understand the Canadian versions are pretty much the same, but they are not called out specifically in any of the factory literature I have so I can’t confirm. I think a lot of the W124s reputation has perhaps run out now, just as they are so old, perhaps based on very nice ones or ten year old info, they are all twenty plus years old, probably the pinnacle of built in quality, engineering and enough modernity so it isnt properly old fashned with carbs etc, but time and miles stll add up, dont assume it will be bulletproof, check it over like any old car. The EZL (ignition module) on the later engines is a bit more problematic and can fail. The compression ratio is raised to 10.5:1. The 722.6xx is pretty good, but the earlier years have some issues. This family of engines was introduced in 1969 with the 3.5l M116 and was followed in 1972 with the 4.5 M117. Those manifolds are very expensive, so I went with what I had. The story goes that Mercedes-Benz were concerned that the introduction of the BMW E32 7 series with its 220KW V12 placed the W126 at a competitive disadvantage. This is located at the front left of the car. This 560 is referred to as the 117.967.
Unlike other Mercedes engines, all versions of the 560 are good. A short history of injection engines – Mercedes-Benz is a pioneer in direct gasoline injection. Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy; its inherent virtue is the equal sharing of misery. The 560 is a longer stroke version of the 500. The aluminum SOHC cylinder heads have 3 valves per cylinder.
