Book Description
The two stroke engines have been around for more than a century and have survived so far, primarily in portable applications. From the beginning, two stroke engines have suffered from poor fuel economy and high fuel emissions compared to the larger, heavier, but more efficient than four stroke design. The scavenging process in the two-stroke engine has direct influence on engine performance on their combustion process and remains one of the important strategies towards improvement of fuel efficiency and reduction of pollutant. The new of engine test rig was design and fabricate for motoring concept a single cylinder 30.5 cc two strokes spark-ignition. Then measurement installation was done to the test engine. It will be the platform for further study in investigation the in-cylinder characteristic whiles the scavenging process for motored condition. The result of this project is a new engine test rig with motored condition for two-stroke spark ignition (SI) engine with instrument installation for data measurement.

Book Description
This book addresses the two-stroke cycle internal combustion engine, used in compact, lightweight form in everything from motorcycles to chainsaws to outboard motors, and in large sizes for marine propulsion and power generation. It first provides an overview of the principles, characteristics, applications, and history of the two-stroke cycle engine, followed by descriptions and evaluations of various types of models that have been developed to predict aspects of two-stroke engine operation.

Book Description
This paper presents research efforts made in three different phases with the objective of improving the fuel economy of and reducing exhaust emissions from conventional, carbureted, two-stroke spark ignition (SI) engines, which are widely employed in two-wheel transportation in India. A review concerning the existing two-stroke engine technology for this application is included. In the first phase, a new scavenging system was developed and tested to reduce the loss of fresh charge through the exhaust port. In die second phase, the following measures were carried out to improve the combustion process: (1) using an in-cylinder catalyst, such as copper, chromium, and nickel, in the form of coating; (2) providing moderate thermal insulation in the combustion chamber, either by depositing thin ceramic material or by metal inserts; (3) developing a high-energy ignition system; and (4) employing high-octane fuel, such as methanol, ethanol, eucalyptus oil, and orange oil, as a blending agent with gasoline. Based on the effectiveness of the above measures, an optimized design was developed in the final phase to achieve improved performance. Test results indicate that with an optimized two-stroke SI engine, the maximum percentage improvement in brake thermal efficiency is about 31%, together with a reduction of 3400 ppm in hydrocarbons (HC) and 3% by volume of carbon monoxide (CO) emissions over the normal engine (at 3 kW, 3000 rpm). Higher cylinder peak pressures (3-5 bar), lower ignition delay (2-4°CA)° and shorter combustion duration (4-10 °CA) are obtained. The knock-limited power output is also enhanced by 12.7% at a high compression ratio (CR) of 9:1. The proposed modifications in the optimized design are simple, low-cost and easy to adopt for both production and existing engines.
