OTTO ENGINE: are internal combustion engines that consume a mixture of gasoline and air has an electric ignition system, an intake and exhaust valves moved x controlling distribution system and consists of 4 times. * ON: the end of the cycle of compression ignites the mixture x through the candle that ignites the mixture .* OTTO ENGINE CONSTITUTION: consisting xa reciprocating piston and a connecting rod and crankshaft, the piston moves x the cylinder consisting of a PMS and PMI that this is the race distance, the cylinder is measured volman well, * pi · voumen Unit = D2 / 4 x race. * Compression ratio: vulumen unitri + chamber volume / chamber volume. * THEORETICAL FOR OTTO CYCLE: admission: the piston goes to pmi pms and while the intake valve is open thus the cylinder is filled with air and fuel when the piston closes lower ends of the crankshaft and a turned back. Compression: stan the valve closed and the piston rises to TDC PMI mixture is compressed in the combustion chamber and a crankshaft turned around. expansion and combustion: mixing and ignites x comñrimida through the candle and this is expanded by lowering the piston TDC at PMI clorifica energy is transformed into mecanica.escape: the piston which is in PMS and PMI rises to the outlet ace open to x the pressure of rising gas piston are released .* diagram of it is the graphic representation of the moments in which the valve opens and closes. EPA: laa exhaust valve opens before the PMI psiton reach this pressure that is generated from 3 to 4 brs ace salgana gases decreases rapidly as the ace that the cylinder pressure rises faster. AAA: The inlet valve opens a few seconds before it reaches pston esl PMS when the exhaust permeanece even abirta. thus the speed of the exhaust trail coming improving the frescoes of the cylinder. RCE: when the nurse started to come down piston the outlet is open, and due to the speed you continue making gas out causing a complete discharge of waste gases. RCA: the piston descends in the gas admission and continue going out and when it starts up due to an inertia that the GSEs made it improves SEGIR entering the cylinder.

DIESEL ENGINE: internal combustion engine in the admison only air and fuel injected has a inyecion system and the inflammation is produced by contact with air that has a lot of temperature due to compression is a 4-stroke engine ( admison air compression, injections, exhaust)
uses diesel fuel mixing occurs in a and 2 l cylinder inyeccions rates. ignition occurs due to the strong compression temepratura generates high air 500 º c l fuel ignites and the load of the cylinder has to be the maximum. * Theoretical DIESEL CYCLE: admission: the lower piston TDC at PMI Edmison the valve is open and air enters. compression: the rise of PMI piton A PMS aciendo compressing the air and who makes himself a high temperature. injection, combustion and expansion: the cylinder is at TDC and the air is very Cali and injects the fuel injector spray and due to high temperature the fuel ignites in the cylinder then low. exhaust: The exhaust valve opens when the piston is at PMI. * SETTLEMENT:
Diesel: maximum admission of air, high temperature at the end of compression, AUTOIGNITION of gases from combustion pressure of 70 to 90 brs. otto a specified proportion of mixture, spark ignition, rapid combustion at constant volume and maximum pressure of 30 to 40 brs. DISTRIBUTION: The distribution includes all the elements that perform the opening and closing valves, which ciboria elemton distribution are the camshaft sprocket, transmission system, guides valve seats, springs and rocker arms and tappets valve timing. of the distribution arrangement: OHV: CAMSHAFT side. OHC and DOHC: camshaft in the Cavez. FORMS crankshaft and working time: 4-cylinder in-line firing order :1-3-4-2 or 1-2-4-3 (picture on the phone). Horizontally opposed 4 cylinder: 1-4-3-2. 5 cylinder interval of 144 th and 1-2-4-5-3. 6 cylinder: 120 ° and 1-5-3-6-2-4 or 1-2-4-6-5-3. 6 cylinders in V: 1-3-6-5-4-2. 8 cylinders in V: 90 ° and 1-5-4-8-6-3-7-2. 12 cylinder W: 60 and 1-12-5-8-3-10-6-7-2-11-4-9
