timing of the ignition was the control variable. The mechanically controlled combustion process was not optimal in terms of fuel efficiency. Modeling of the combustion process showed‚ for increased fuel efficiency‚ there existed an optimal time when the fuel should ignite. The timing depends on load‚ speed‚ and other measurable quantities. The electronic ignition system was one of the first mechatronic systems to go in the automobile in the late 1970s. The electronic ignition system consists

The application of Digital twin spark ignition technology can eliminate this problem up to maximum extent.

Introduction: The quantity of organic matter in soil is determine by either direct or indirect methods. Direct method target the destruction of all organic matter‚ after which the loss in weight of soil is taken as the organic content. Two methods are commonly used to achieve destruction of organic

English II 4/27/13 Alcohol Interlocks Saving Life’s Ignition interlocks have been issued in forty-eight states. Presented on June 22‚ 2000 by Pennsylvania‚ Ignition interlocks are similar to in-car breathalyzers that measure a driver’s blood alcohol concentration (BAC). They prohibit the engine from starting if an alcohol-sensing device registers above a pre-set level‚ typically around 0.02 BAC. This ignition interlock act started at one state‚ from there it eventually

1. DEMERIT POINT SYSTEM Demerit points are added to your driver’s licence‚ if you are convicted of breaking certain driving laws. The rules are different depending on if you are a new driver or have a full licence. This information will explain how the demerit points system works. How demerit points work You don’t “lose” demerit points on your driving record. You start with zero points and gain points for being convicted of breaking certain traffic laws. Demerit points stay on your record for

FUEL OIL BURNERS By Mark Butterfield March 09 INTRODUCTION The history of burners dates back to the early shipping days‚ when fuel oil first started replacing coal as the ships’ primary fuel source. Since then‚ burner designs and construction have come a long way‚ but the principles behind their operation has remained the same. All makes and types of burners have two things in common They need to atomise the fuel They need to mix the fuel with the air needed for combustion

if they are driving without a license they would at least be sober. When you think about the statistics of how many innocent people lose their lives every year‚ installing breathalyzers doesn’t seem like a bad idea. The breathalyzer is an ignition interlock device that will test a driver’s breath to determine their blood alcohol level. This device requires the driver to blow into a small hand held unit that is attached to the dashboard. The device has an alcohol sensor that records a digital
