Modern engines. Part 1

Most recently began selling a very interesting car - Mazda 3 MPS, apparently not very different from the usual "treshki. But the internal filling, compared with the civilian version, differs substantially. Still, front-drive car for the first time can be seen in action and try new engine - MZR 2.3 DISI Turbo with a capacity of 260 liters. with. and a torque of 380 Nm, available already from 3000 rpm. The new management program is responsible for not only the injection and ignition systems, but also the throttle and turbine bypass valve on certain conditions. Excess capacity, a relatively high compression ratio for turbo engine - 9.5, and direct fuel injection makes turboyamu almost invisible. Gasoline is injected under high (115 bar) pressure in the combustion chamber, creates a positive cooling effect, which enhances the volumetric efficiency. Therefore, torque, developed MZR 2.3, more than a similar engine with a standard multi-point injection. The system of variable valve timing to optimize S-VT angles of opening and closing valves in accordance with the regime of motion. Direct injection allows a more homogeneous mixture around the spark plug to avoid gaps in the cylinders. Turbocharger - also a new design, relatively light weight counterparts, which allows it to spin up faster and increase the power characteristics. For the power plant of this size are impressive power and torque, so the materials for the manufacture of MZR 2.3 to appropriate. Block and cylinder head fabricated using advanced precision molding (know-how from Mazda). To optimize the thermal process has increased the number of cavities between the walls of the cylinders. Connecting rods and crankshaft are made from high strength steel, used a fully floating piston pins. Good job Mazda company over its creation. Manufacturing extraordinary engines - the old-horse of this company. Interestingly, the first MZR 2.3 is installed on the Mazda 3, although earlier it was believed that more than 250 liters. with. for front wheel drive car of this class - it's just dangerous. In general, the charged hatchback is a really very skittish, despite the numerous safety systems and a limited slip differential. In any case, if you have a head on their shoulders to manage such a fireball can be happy. Later, the engine began to be put on the Mazda 6, and the weighty Mazda CX-7. Despite the increased weight agregatonositeley, as is the case with the CX-7 - and the use of all-wheel drive, the engine does not pass, presenting all these enviable model dynamics. What more pleasing model Mazda, so it is quite reasonable price for extraordinary performance. Nor must it be forgotten that powerful engine assumes the costs of fuel, especially during the active use of the gas pedal. At one time the company has repeatedly been accused of extravagance engines, especially with regard to their rotary piston power units. As so, the volume - 1.3 liters, and flow rate - 15-16 litres/100 km?
