DTC P0341 Camshaft Position (CMP) Sensor Performance
1998 Chevrolet/Geo Malibu DTC P0341 Camshaft Position (CMP) Sensor Performance Circuit Description During cranking, the Ignition Control Module (ICM) monitors the 7X crankshaft position sensor signal. Once the ICM determines spark synchronization, 3X reference signals are sent to the PCM. The PCM will command all six injectors ON for one priming shot of fuel in all cylinders. After the priming, the injectors are left OFF for the next six fuel control reference signals (two crankshaft revolutions). This allow each cylinder a chance to use the fuel from the priming shot. During this waiting period, a cam pulse will have been received by the PCM. The PCM uses the Cam signal pulses to initiate sequential fuel injection. The PCM constantly monitors the number of pulses on the Cam signal circuit and compares the number of Cam pulses to the number of 24X reference pulses and the number of 3 X reference pulses being received. If the PCM receives an incorrect number of pulses on the Cam reference circuit, DTC P0341 will set and the PCM will initiate injector sequence without the Cam signal with a one in six chance that injector sequence is correct. The engine will continue to start and run normally, although the misfire diagnostic will be affected if a misfiring condition occurs. Conditions for Setting the DTC z The engine is running (3X reference pulses are being received). z CMP sensor reference pulse is not detected every engine cycle. Action Taken When the DTC Sets z The PCM will illuminate the malfunction indicator lamp (MIL) during the second consecuitive trip in which the diagnostic has been run and failed. -

Effect of Using Biodiesel As a Fuel in C I Engine
International Journal of Engineering Science Invention ISSN (Online): 2319 – 6734, ISSN (Print): 2319 – 6726 www.ijesi.org ||Volume 5 Issue 7|| July 2016 || PP. 71-81 Effect of Using Biodiesel as a Fuel in C I Engine Swagatika Acharya1, Tatwa Prakash Pattasani2, Bidyut Prava Jena3 1,2Assistant Professor, Department of Mechanical Engineering, Gandhi Institute For Technology (GIFT), Bhubaneswar 3 Assistant Professor, Department of Mechanical Engineering, Gandhi Engineering College, Bhubaneswar Abstract: Biodiesels are fuels that are made from renewable oils that can usually be used in diesel engines without modification. These fuels have properties similar to fossil diesel oils and have reduced emissions from a cleaner burn due to their higher oxygen content. The present work investigates the performance of three types of biodiesel and diesel fuels in a Mitsubishi 4D68 4 in-line multi cylinder compression ignition (CI) engine using transient test cycle. The test results that will obtain are brake power, specific fuel consumption (SFC), brake thermal efficiency and exhaust emissions. An instrumentation system also will be developed for the engine testing cell and controlled from the control room. Biodiesel was also tested against diesel fuel in Exhaust Gas Recirculation (EGR) system. Thus it is possible that biodiesel fuels may work more effectively than fossil diesel in certain applications. Keywords: Biodiesel, CI engine, transient, Instrumentation, EGR I. Introduction Biodiesel, is the generic terms for all types of Fatty Acid Methyl Ester (FAME) as one among other organic renewable alternative fuel that can be used directly in any conventional diesel engine without modification. They are transesterified vegetable oils that have been adapted to the properties of fossilized diesel fuel and considered to be superior since they have a higher energetic yield been combusted in the diesel engine (Adams 1983) . -

3.0 ACTUAL ENGINE CYCLE Reciprocating Internal Combustion
3.0 ACTUAL ENGINE CYCLE Reciprocating internal combustion engines operate on actual engine cycles, which are classified mainly into two groups: (i) Spark Ignition engines and (ii) Compression Ignition engines and these classifications are dependent on the mode of the ignition of the air/fuel mixture (charge) in the cylinder. The spark ignition engines operate based on the Otto cycle principle while the compression ignition engines operate basically on the Diesel cycle principle. The sequence of operations required by a reciprocating engine to perform a mechanical work could either be two or four strokes of engine piston motion which translates to one or two crankshaft revolution respectively. The piston of a reciprocating internal combustion engine could be termed as double acting (as seen in steam engines) or single acting (as is seen in most reciprocating internal combustion engines). If the engine cycle of operation takes place in only one side of the piston, its termed single acting while it is termed double acting when the cycle takes place on both sides of the piston. For an internal combustion engine to be efficient the following requirements are to be met: The mixture of fuel and air in the engine cylinder must be in the right proportion. Compression must take place on the mixture of air and fuel or air only before the addition of fuel (this is dependent on the engine cycle operation). The compressed mixture is to be ignited (which could be through the introduction of spark or auto-ignition) and the expanding combustion products used to drive the engine. -
