A new heat insulated natural gas engine was developed. In this engine, a pre-chamber and a main chamber are connected with a passage which is equipped with a valve. The passage is closed during the intake stroke, the pre-chamber is charged with low pressure natural gas, and air is directed into the cylinder. The valve functions to open the passage near the TDC, the compressed air flows into the pre-chamber, air and natural gas mix together and burn. Testing showed that there is no need of ignition systems, and that high thermal efficiency can be obtained. ,"~ Society of Automotive Engineers of Japan, Inc. and Elsevier Science B.V.

In this work a methodology is presented for studying the influence of the addition of small percentages of hydrogen in spark-ignition engines running on natural gas, on CO and the NOx exhaust emissions. Thermo-chemical models are used to predict the exhaust emissions. The general inputs of these mod
