SWEngines - Providing Best Used Engines with Warranty Internal combustion engine is commonly used in automobiles, trucks and buses. It converts chemical energy of the fuel into thermal energy that can be used for useful mechanical work. Combustion chamber is a vital part of the working fluid circuit of an internal combustion engine. Examples of internal combustion engine include piston engines, gas turbines engines and rocket engines. Principle of engine operation Air and fuel mixture in the inside the cylinder is ignited either by a spark plug or compression. This ignition generates high level of heat and pressure in the combustion chamber which induces reciprocating motion in the piston. Types of internal combustion engines Internal combustion engines can be classified on multiple criteria like: Application
Automotive (Car, truck, bus and off-highway) Locomotive Light Aircraft Marine (outboard, inboard and ship)
Power Generation Portable (domestic) Fixed ( peak power) Agricultural Tractors Pump sets Earthmoving
Dumpers Tippers
Home use
Lawnmowers Snow blowers Tools
Basic engine design: There are two basic engine designs, viz. Reciprocating and Rotary Reciprocating
Single cylinder Multi-cylinder Multi-cylinder engine can be further divided into the following based on the alignment of cylinders in it like:
In-line V Radical Opposed cylinder Opposed piston
Rotary engine has the following two variants: Single Rotor Multi-rotor Based on Operating Cycle, engines can be classified as:
Otto (for conventional spark ignition engine) Atkinson (for complete expansion spark ignition engine) Miller (for early or late inlet valve closing type spark ignition engine) Dual (for actual diesel engine) Diesel (for ideal diesel engine)
Working cycle (strokes) Engines are also categorized into two stroke and four stroke based on their working cycle. Two stroke cycle It has following variants: 1.
Crankcase Scavenged Uniflow Scavenged Inlet valve or exhaust port Inlet port or exhaust valve Inlet and exhaust valve
Four stroke cycle Naturally aspirated Supercharged or Turbocharged Engines are also classified on the basis of valve design and location. Engines are categories based on valve and port design as: Poppet valve
Rotary valve Reed Valve Piston controlled porting Valve location
The T-head The L-head The F-head The I-head Overhead valve Overhead cam
Engine classification based on Fuel Conventional a. Crude oil derived i) Gasoline ii) Diesel b. Other sources i) Coal ii) Wood iii) Shale iv) Tar Sands Alternate a) Gasoline derived i) LPG ii) CNG b) Bio-mass derived i) Vegetable oil ii) Biogas iii) Hydrogen iv) Ethanol Classification based on Mixture Preparation: Carburetion Fuel injection a. Diesel b. Gasoline i) Port ii) Manifold iii) Cylinder Classification based on Method of Ignition: Spark Ignition (homogenous charge) a) Conventional i) Magneto ii) Battery b) Other methods and techniques Compression Ignition (heterogeneous charge)
Compression Ignition (homogenous charge) Combustion chamber design Open chamber i) Wedge ii) Hemispherical iii) Disc type iv) Bowl-in-piston Divided chamber For Compression Ignition i) Swirl chamber ii) Pre-chamber For Spark Ignition i) CVCC ii) Other designs Method of cooling: Water cooled Air cooled Uncooled (other than by natural convection and radiation) Engines develop various problems no matter how well you maintain them due to regular wear and tear, overuse or abuse. This ultimately lowers its performance and you will have to pay regularly in fixing these issues.

"Swengines.com surpassed my expectations with the quality of the engine. They were up front regarding how long it would take and the cost wasn’t necessarily the cheapest but I can firmly say I would not have done it any other way if I had to do it over again." - Paul J. , Illinois "We purchased a 2004 Audi A4 Engine a couple weeks ago. All has been installed and just wanted to touch base with you guys and let you know it was a pleasure doing business with you. I’ll be sure to put the word out to my friends when and if they ever need a replcement engine. Thanks!" - Scott R. , California "We just wanted to inform your company that we have received both the 2008 Camry Engines. Both were in very great shape totally ready to install. We’ve had both engines installed at this point and they are both running great!. It did take longer than we hoped to get them here but we now undersand the type of care you guys go through to make things right. thanks guys! (and gals :-))" - Rick M. , Georgia
