MERCEDES-BENZ 3.5 M272

The Mercedes-Benz M272 engine is a V6 automobile piston engine family used in the 2000s (decade). Introduced in 2004, it is based on the M112 V6 introduced in 1998. All M272 engines have aluminum engine blocks with a 90° vee angle with silicon/aluminum lined cylinders. The aluminum DOHC cylinder heads have 4 valves per cylinder. Direct injection is used in a limited fashion on the 3.5 L V6, whereas others use conventional port fuel injection. All have forged steel connecting rods, one-piece cast crankshaft, iron-coated aluminum pistons and a magnesium intake manifold. Like the M112, a balance shaft is installed in the engine block between the cylinder banks to deal with vibrations in the 90 degree V6 design. This essentially eliminates first and second order moments. A dual-length Variable Length Intake Manifold is fitted to optimize engine flexibility. Continuous VVT was adopted for the first time. Featured on both the intake and exhaust camshafts, each can be varied through a range of 40 degrees. The twin spark plug system was replaced by a regular single spark plug per cylinder. New electronic coolant flow control has replaced the mechanical thermostat for improved engine warm-up and optimum control of engine temperature. Also tumble flaps are used to improve output at low engine speeds. The E35 is a 3.5 L (3498 cc) version. Bore dimension is 92.6 mm and stroke is 86 mm. Output is 272 PS (268 hp/200 kW) at 6000 rpm with 258 ft·lbf (350 N·m) of torque at 3500 rpm. A direct injected variant debuted in 2006 under the name Stratified-Charged Gasoline Injection (CGI). First fitted to the CLS350 CGI, it produces 292 PS (288 hp/215 kW) and 269 ft·lbf (365 N·m) of torque while lowering fuel consumption. In 2008, the non-CGI engine was uprated to 316 PS (232 kW) at 6500 rpm and 265 ft·lbf (360 N·m) of torque at 4900 rpm. This was achieved by raising the rev-limit to 7200 rpm, increasing the compression ratio and other modifications to the valvetrain.[WIKI]
