Two stroke engine development

U ovom završnom radu obuhvaćena je i razrađena tema dvotaktnog motora s direktnim ubrizgavanjem. Kao podlogu za podatke koristio sam KTM-ov EXC 250 TPI model te Yamaha YZ 250. Izneseni su glavni problemi koje prate klasične dvotaktne motore te njihova potencijalna rješenja kombiniranjem znanja stečenog na faksu, u slobodno vrijeme te doma sa ocem u garaži. Rad obuhvaća termodinamički proračun , sklopni i radionički nacrt koji su priloženi uz rad, te simulaciju u programu Lotus.In this dissertation the topic of a two-stroke direct injection engine is included and elaborated. As a basis for data, I used KTM's EXC 250 TPI model and Yamaha YZ 250. The main problems that accompany classic two-stroke engines and their potential solutions are presented by combining the knowledge acquired in college, free time and at home with my father in the garage. The dissertation includes a thermodynamic calculation, assembly and workshop design that are attached to the dissertation, and a simulation in Lotus
