  • Poppet Valve
    POPPET VALVE A poppet valve is a valve consisting of a hole, usually round or oval, and a tapered plug, usually a disk shape on the end of a shaft also called a valve stem. The shaft guides the plug portion by sliding through a valve guide. In most applications a pressure differential helps to seal the valve and in some applications also open it. Other types Presta and Schrader valves used on tires are examples of poppet valves. The Presta valve has no spring and relies on a pressure differential for opening and closing while being inflated. Uses Poppet valves are used in most piston engines to open and close the intake and exhaust ports. Poppet valves are also used in many industrial process from controlling the flow of rocket fuel to controlling the flow of milk[[1]]. The poppet valve was also used in a limited fashion in steam engines, particularly steam locomotives. Most steam locomotives used slide valves or piston valves, but these designs, although mechanically simpler and very rugged, were significantly less efficient than the poppet valve. A number of designs of locomotive poppet valve system were tried, the most popular being the Italian Caprotti valve gear[[2]], the British Caprotti valve gear[[3]] (an improvement of the Italian one), the German Lentz rotary-cam valve gear, and two American versions by Franklin, their oscillating-cam valve gear and rotary-cam valve gear. They were used with some success, but they were less ruggedly reliable than traditional valve gear and did not see widespread adoption. In internal combustion engine poppet valve The valve is usually a flat disk of metal with a long rod known as the valve stem out one end.

  • Overview the Ignition System Is Designed to Ignite the Compressed
    « 1: Description and Operation» Overview The Ignition System is designed to ignite the compressed air/fuel mixture in an internal combustion engine by a high voltage spark from an ignition coil. The ignition system also provides engine timing information to the powertrain control module (PCM) for proper vehicle operation and misfire detection. Integrated Electronic Ignition System The Integrated Electronic Ignition (EI) system consists of a crankshaft position (CKP) sensor, coil pack(s), connecting wiring, and PCM. The Coil On Plug (COP) Integrated EI System uses a separate coil per spark plug and each coil is mounted directly onto the plug. The COP Integrated EI System eliminates the need for spark plug wires but does require input from the camshaft position (CMP) sensor. Operation of the components are as follows (Figure 49): 1. NOTE: Electronic Ignition engine timing is entirely controlled by the PCM. Electronic Ignition engine timing is NOT adjustable. Do not attempt to check base timing. You will receive false readings. The CKP sensor is used to indicate crankshaft position and speed by sensing a missing tooth on a pulse wheel mounted to the crankshaft. The CMP sensor is used by the COP Integrated EI System to identify top dead center of compression of cylinder 1 to synchronize the firing of the individual coils. 2. The PCM uses the CKP signal to calculate a spark target and then fires the coil pack(s) to that target shown in Figure 50. The PCM uses the CMP sensor not shown in Figure 50 on COP Integrated EI Systems to identify top dead center of compression of cylinder 1 to synchronize the firing of the individual coils.

The ultimate solution for engine swaps and serious performance applications, FAST® has put together the first ever supercharger and valve train packages from two of the automotive aftermarket’s biggest brands – Edelbrock® and COMP Cams®. The FAST® engineering team extensively dyno tested various combinations of camshaft specs, valve springs and supercharger pulleys to optimize the power and efficiency of the Edelbrock® superchargers. Dyno testing on a stock head 6.2L LS3 engine produced over 850 HP when running with E85 fuel. The FAST® Supercharger & Cam Power Packages include a pump gas friendly supercharger pulley for engine break-in, initial tuning and general performance driving, while a smaller pulley is also included when maximum power is desired on race fuel or E85. For those wishing to further fine tune boost levels, additional pulley sizes are available. Packages include the basics required to install the supercharger, but necessary accessory items such as fuel injectors, air intakes and heat exchanger pumps are left up to the installer, providing total flexibility for custom installations. The Edelbrock® Supercharger Kits include a 2300 TVS supercharger w/ integrated intercooler. The intercooler is a high capacity, dual bar and plate design that enables major power gains through lower inlet air charge temps. Also included are COMP Cams® application specific cam kits that contain state of the art Low Shock Technology™ Camshafts designed specifically for supercharger applications, along with perfectly matched pushrods, valve springs, retainers, locks, seats and seals.

  • Software Controlled Stepping Valve System for a Modern Car Engine
    Available online at www.sciencedirect.com ScienceDirect Procedia Manufacturing 8 ( 2017 ) 525 – 532 14th Global Conference on Sustainable Manufacturing, GCSM 3-5 October 2016, Stellenbosch, South Africa Software Controlled Stepping Valve System for a Modern Car Engine I. Zibania, R. Marumob, J. Chumac and I. Ngebanid.* a,b,dUniversity of Botswana, P/Bag 0022, Gaborone, Botswana cBotswana International University of Science and Technology, P/Bag 16, Palapye, Botswana Abstract To address the problem of a piston-valve collision associated with poppet valve engines, we replaced the conventional poppet valve with a solenoid operated stepping valve whose motion is perpendicular to that of the piston. The valve events are software controlled, giving rise to precise intake/exhaust cycles and improved engine efficiency. Other rotary engine models like the Coates engine suffer from sealing problems and possible valve seizure resulting from excessive frictional forces between valve and seat. The proposed valve on the other hand, is located within the combustion chamber so that the cylinder pressure help seal the valve. To minimize friction, the valve clears its seat before stepping into its next position. The proposed system was successfully simulated using ALTERA’s QUARTUS II Development System. A successful prototype was built using a single piston engine. This is an ongoing project to eventually produce a 4-cylinder engine. ©© 2017 201 6Published The Authors. by Elsevier Published B.V.

  • Camshaft Degreeing Instructions Intake Centerline Method
    Auto 64HP Camshaft Degreeing Instructions Intake Centerline Method - To verify the location of the intake centerline in reference to the piston position Step 1: Install the camshaft and timing set. Make sure that the timing marks on the cam and crank sprockets are aligned Step 2: Install the intake lifter for cylinder #1 Step 3: Attach the degree wheel to the crankshaft snout or balancer Step 4: Attach a pointer to the front of the block and position just on the outside of the degree wheel Step 5: With the #1 piston down in the cylinder bore, install a piston stop over the cylinder. Rotate the crankshaft until the piston touches the piston stop and mark the degree wheel adjacent to the pointer. Rotate the crankshaft the opposite direction so the piston travels down and back up to the piston stop. Make a second mark adjacent to the pointer Step 6: Remove the piston stop after marking the two points on the degree wheel. Rotate the crankshaft to the midpoint of the two marks. This point is TDC for cylinder #1. Without rotating the crankshaft, adjust the degree wheel to read 0 degrees at the pointer. You are now ready to locate the intake lobe centerline relative to TDC. This step is critical to proper cam alignment Step 7: Attach the dial indicator to the dial indicator mount. Position the dial indicator on the outer edge of the intake lifter. It is important that the indicator plunger be parallel to the lifter. Any variance in the angle of the indicator will introduce errors into the lift readings Step 8: Rotate the engine in the normal direction of rotation until you reach maximum lift.
