Thursday, September 7th, 2017 | Sports

(World Motorsport) – World Champion in Misano: Before the Ducati home race at the Grand Prix of San Marino, the Italian manufacturer presented its new 90-degree this Thursday -V4 engine for the first time to the public. The "Desmosedici Stradale" baptized four-cylinder is inspired directly by the MotoGP racing engine and is to fuefully the previous V2 Superbikes. "It is the first time that Ducati has been equipped with a V4 engine" We are proud to present this technological breakthrough, which marks the beginning of a new chapter in our company and underscores our unwavering commitment to invest in new products, Ducati CEO Claudio Domenicali comments on the new development. "This engine also demonstrates the close interaction between Ducati Corse and the factory, proving the importance of racing for technological development." On 5 November, the new Panigale V4 will be presented at the world's largest motorcycle fair in Milan. Some technical details of the new engine were already revealed on Thursday. The engine is equipped with a slightly larger engine displacement than its MotoGP equivalent, precisely 1,103 cubic centimeters, in order to achieve a particularly good throughput capacity even in the medium and low speed range.Ducati starting from 2019 with V4 Superbikes at the startIn the top, the Euro- 4 engine delivers more than 155 kW (210 hp) at 13,000 rpm, while it always applies more than 120 newton meters of torque to the crankshaft in a particularly important speed range between 8.750 and 12.250 rpm. The "Twin Pulse" sequence, in which the two right and the two left cylinders close almost simultaneously, is a particularly well controllable one Power development of the engine. Like the units used by the MotoGP, it is installed 42 degrees backward to distribute the weight more optimally. A compensating shaft is therefore superfluous. The Duromati typical desmodromic valve control, on the other hand, must not be missing. An R version with less than 1,000 cubic centimeters displacement is already under development. This will turn up and be aligned accordingly for use on the race track. In 2019, she will be debuting in the Superbike World Cup. At the end of the coming season, Ducati will finally adopt the long-term V2 concept. The competition has long been based on a 1000-cylinder engine.Technical data- 1.103 cm 90 degree V4 cylinder engine bore x stroke 81 x 53.5 mm compression 14: 1 Maximum output over 210 hp (155 kW) at 13,000 rpm – max Torque over 120 Nm between 8.750 and 12.250 / min- Euro 4- two overhead camshafts with chain-gear hybrid drive- dermodromic valve control, four valves per cylinder-opposing crankshaft with 70 degree reciprocating offset multi-disc lumbi clutch with servo function semi-dry sump lubrication with four pumps – one pressure pump and three backflushing pumps
