4 Stroke Engine

Edit: I know Im spinning it backwards. There was an arrow that misled me when I took this video. This is an example of a 4 stroke(Otto Cycle) Heat Engine. Visible is the cylinder with surrounding water passages(cooling system routed to radiator) Valve train, which is control by the two cams attached to the smaller gears, and the crankshaft which is attached to the larger gear and is connected to the piston through connecting rods. If one pauses at the end, the Otto Cycle chalkboard work is visible, where the isothermal and adiabatic processes required to produce the net work are expressed. (Taken from Giancoli Ch. 20) The cycle is as such: a)the gasoline-air mixture flows into the cylinder as the piston moves down. b)the piston moves upward and compresses the gas c)the brief instant when firing of the spark plugignites the highly compressed gasoline-air mixture raising it to a high temperature d)the gases, now at high temperature expand against the piston(in the power stroke) e) the burned gases are pushed out to the Exhaust pipe; when the piston reaches to the top, the Exhaust valve opens, and the whole cycle repeats. a, b, d, and e are the four strokes of the cycle. There is a minor discrepancy in the mechanics of this particular demo; it's cranked the wrong way.

Octane Ratings and the 4 Stroke Engine Cycle - EricTheCarGuy
I know it has been a while but better late than never. I recently had a conversation with someone who wanted to know why octane ratings were important and what they meant, I thought this would make a perfect video for ETCG and here we are. So in this video we go over the 4 parts of the 4 stroke cycle in a gasoline engine and how it is effected by octane. I like this video because it is a window into the direction I see these videos going in the future, more dynamic and more thought out. I hope you enjoy it and find it informative. Special thanks to Ford Motor Company for the use of their animation in this video. I did add some stuff of my own by the way, thanks guys. --- Click below and Stay Dirty Visit me at EricTheCarGuy.com http://ericthecarguy.com/ Visit EricTheCarGuy Forum http://www.ericthecarguy.com/forum/default.aspx Visit my Facebook Page: http://www.facebook.com/EricTheCarGuy --- BTW Keep checking back with EricTheCarGuy.com, in the not too distant future I will be updating the site and making more in dept videos available for purchase.

Awesome V12 Monster diesel engine Awake and Alive startup
Awesome V12 Monster diesel engine Awake and Alive startup The first V-type engine (a 2-cylinder vee twin) was built in 1889 by Daimler, to a design by Wilhelm Maybach. By 1903 V8 engines were being produced for motor boat racing by the Société Antoinette to designs by Léon Levavasseur, building on experience gained with in-line four-cylinder engines. In 1904, the Putney Motor Works completed a new V12 marine racing engine -- the first V12 engine produced for any purpose.[2] Known as the 'Craig-Dörwald' engine after Putney's founding partners, the engine mounted pairs of L-head cylinders at a 90 degree included angle on an aluminium crankcase, using the same cylinder pairs that powered the company's standard 2-cylinder car. A single camshaft mounted in the central vee operated the valves directly. As in many marine engines, the camshaft could be slid longitudinally to engage a second set of cams, giving valve timing that reversed the engine's rotation to achieve astern propulsion. "Starting is by pumping a charge into each cylinder and switching on the trembler coils. A sliding camshaft gave direct reversing. The camshaft has fluted webs and main bearings in graduated thickness from the largest at the flywheel end."[3] Displacing 1,119.9 cuin (18,352 cc) (bore and stroke of 4.875" x 5" (123.8 x 127 mm)), the engine weighed 950 pounds (430 kg) and developed 150 bhp (110 kW). Little is known of the engine's achievements in the 40-foot hull for which it was intended, while a scheme to use the engine to power heavy freight vehicles never came to fruition.[2] One V12 Dörwald marine engine was found still running in a Hong Kong junk in the late-1960s. Two more V12s appeared in the 1909-10 motor boat racing season. The Lamb Boat & Engine Company of Clinton, Iowa built a 1,558.6 cuin (25,541 cc (5.25" x 6" (133.4 x 152.4 mm)) engine for the company's 32-foot Lamb IV. It weighed in at 2,114 pounds (959 kg). No weight is known for the massive 3,463.6 cuin (56,758 cc) (7" x 7.5" (177.8 x 190.5 mm)) F-head engine built by the Orleans Motor Company. Output is quoted as "nearly 400 bhp (300 kW)". By 1914, when Panhard built two 2,356.2 cuin (38,611 cc) (5" x 10" (127 x 254 mm)) engines with four-valve cylinder heads the V12 was well established in motor boat racing.[2] In automobiles, V12 engines have not been common due to their complexity and cost. They are used almost exclusively in expensive sports and luxury cars because of their power, smoother operation and distinctive sound. ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ ▬▬ ★ MORE INTERESTING VIDEOS: http://www.youtube.com/watch?v=yrbwGmtZ8pM&list=UUYH8swcp71EHt-88lkaMDTQ ★ SUBSCRIBE: http://goo.gl/GynuUU ★ Follow my Twitter: https://twitter.com/GeorgeDominik1 ★ Thanks For Watching ★ ★ Post comment , share and tell us what u think ★ ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ ▬▬
