Types of used car engines in the market

 

Car engines have come a long way. While some people prefer powerful engines others value engines that provide fuel efficiency. Car manufacturers have designed and are continuously designing different kinds of engines that meet the highest standards in efficiency, performance and fuel management.  As we discuss the different engine types, you must understand that it is a mechanical device that is given to wear and tear. Engines are one of the most expensive and important parts of the vehicle. Instead of investing in OEM engines, investing in quality used engines from reliable vehicle engines and parts online store is a wise investment. While saving thousands of dollars you are assured of high-quality used car engines that last as long as an OEM engine.

Internal combustion Engines 

• This is a type of engine where fuel combustion takes place. 
• As the fuel burns inside the engine the temperature increases producing high pressure.
• This high pressure produced by combustion is applied to the piston, rotor, and nozzle. 
• The force produced from the pressure moves the car. 
• The chemical energy is transformed into mechanical energy.
• These engines are used in power cars.
• The internal combustion engine is evaluated on various variables like ignition type, number of stokes and design. 
• Internal combustion used engines for sale are available at reliable online used engine stores.
  

Two-stroke engines

• In this type of engine, the piston’s two strokes complete a power cycle. 
• Going up once and down inside the cylinder, the crankshaft revolution is complete for the fuel to burn a single time. 
• The end and the beginning of the combustion stoke take place at the same time. 
• The intake and the exhaust function happen simultaneously. 
• The torque in two-stroke engines is higher than a four-stroke engine.
  

Four-stroke engines

• In this internal combustion engine, the piston completes four strokes when turning a crankshaft.
• In a four-stroke, the piston moves up and down inside the cylinder and the crankshaft completes two revolutions.
• This is a stronger engine compared to a two-stroke engine.

• These batteries power the engine and other electric vehicle components. 
• The electric motor converts the electric energy to mechanical energy.
• They show higher onboard efficiency than diesel engines.
• Most electric cars use lithium-ion or lead-acid batteries
  

HCCI (Homogenous Charge Compression Ignition)

• With maximum fuel efficiency and minimum emission, this is a combination of gasoline and diesel engine. 
• These engines are hybrid solutions.
• The engine’s reduced temperature does not burn the fuel completely causing negligible nitrogen oxide emission. But the carbon monoxide and hydrocarbon emissions are high.

Single-cylinder engine 

• These engines come in one cylinder connected to the crankshaft.
• They are lightweight and are found in motorcycles.
  

Multiple cylinder engines 

• Opposite of single-cylinder engines, these are either two or four-stroke engines. 
• They can be diesel or spark ignitions engines. 
• These achieve higher revolutions per minute and can neutralize imbalance more efficiently.
  

Inline engine 

• The cylinders in these engines are arranged in a straight line. 
• They are arranged one behind the other along the length of the crankshaft. 
• The inline-four engine is the most popular in the auto industry.
• This is compact and power-efficient in terms of weight and ratio from a six or eight-stroke engine.
  

V engine

• The cylinder and piston align to form a V on two separate planes. 
• This shape reduces engine weight and length when compared to inline engines.
  

W engine 

• This engine, used in Volkswagen uses a W or double V-shaped engine.
• This has three configurations.
• The configuration uses three banks of cylinders with a common crankshaft.

Resembling the British broad arrow mark.

• The second has four banks of cylinders with a common crankshaft.

This is also called the double V.

• The third has two banks of cylinders with two crankshafts. 

The W engines are used in Volkswagen cars and feature in Bugatti Veyron. 

OPOC engines 

• The opposed cylinder and opposed-piston engines have two cylinders and a piston at both ends.
• This engine has no cylinder head and no valves.
• The bearing load is low with less friction. 
• Being small it has high power to weight ratio.
  

Naturally aspirated engines 

• The air intake depends on atmospheric pressure.
• The engine does not depend on forced induction through a turbocharger or supercharger. 
• The naturally aspirated engine is used by sports cars as this engine has no turbo lag. 
• The petrol engine, small engines required for non-automotive purpose use this engine.
  

Supercharged turbocharged engine

• A supercharge uses a crankshaft for energy to produce power as opposed to turbochargers that exhaust stream.
• Supercharges connect with a belt to the engine and can achieve a speed up to 50,000 RPM.
• Turbocharges not being directly connected to engines can pick up speed up to 15,000RPM. 
• The turbocharger has smog altering equipment and has recoded low carbon emission, therefore more ecofriendly than superchargers.

What Should You Know When Purchasing An Engine Control Module?

 

An engine part may need a replacement for several reasons. Replacing engine parts like an Engine Control Module with a new one is expensive; a used part could help you save on the cost. Selecting a used ECM is not a bad idea if you buy from the right place. Salvage yards or junkyards may store used car engines and their parts, but you cannot be too sure about the part's history. The part's condition too would be unknown to you if you are not an expert. Buying used engines or engine parts come with some undeniable risks, but you can reduce the risk if you know what to check when buying the used engine parts. 

What is an Engine Control Module?

• It is a component of any automotive mechatronic system.
• This unit controls both engine and transmission.
• Also called the Engine Control Unit ECU, it controls the injection of the fuel.
• The engine's crankshaft position sensor determines the position of the engine observing if the injectors and ignition system are activated at the exact time.
• The ECU keeps the mixture of air and gas tightly controlled in modern cars, replacing the earlier carburetor, more intelligently.
• The ECU controls the fuel injection, ignition and ancillaries of the engine.
• It uses digitally stored equations and numeric tables doing away with analogue means. 
  

What variables does the ECU deal with within the perfect ratio?

• The engine's demand.
• The coolant and engine temperature.
• The air temperature.
• The temperature of the fuel. 
• The quality of the fuel.
• Varying filter restriction.
• Meeting the air pressure.
• Observing the engine's pumping efficiency.

The working of the ECU

• The ECU is the brain of the engine., a computer that is responsible for power management on a limited scale. 
• It comprises temperature and pressure sensors, on/off signals, and data from other modules within the vehicle. 
• It collects the information and makes decisions. 
• Once the data is collected by the ECU from the software stored in its unit, it processes depending on output specifications like the fuel injector pulse width.
• The processor leads the software to decide on the appropriate output and records specifications like mixture adjustment and mileage.
• These help the ECU to perform the necessary action on the engine by dispensing the precise power to control the actuators.
• It includes the control of fuel injector pulse width, the exact timing of the ignition system, opening of an electronic throttle body or the activation of a radiator cooling fan.
• The ECU, to function properly, needs internal power and many internal components. 

ECU basic function

• ECU need sophisticated power management.
• It has a variety of components.
• The ECU regulates 1.8V, 2.6V, 3.3V, 5V, 30V and up to 250V of cars from the 10-15V supply.
• The ECU has full control over its power management till the ignition is on.
• When it receives the correct voltage, the microprocessor boots up and reads software from memory doing a self-check.
• Reading data from several sensors in the engine converts them into useful information.
• The CANbus, an internal computer car network that transmits information to other electronic modules. 
• Once the information has been interpreted by the microprocessor, it activates the output based on the numeric tables and formulae within the software.
  

The ECU is monitored individually by its microprocessor that determines the readings within the tolerance level. If the sensor readings fail and fall out of the tolerance level beyond the predetermined time, a fault is registered, and the fault code is retrieved by a technician.

What are fault codes?

Logic within the software is skipped or bypassed with a fluctuation in the engine efficiency when the engine is still working at a basic level. Sometimes the fault is determined at the self-diagnosis level and the engine automatically shuts down for safety.

Technicians access the fault codes after a diagnosis into the ECU memory. The fault code is a 5-digit alphanumeric code that starts with P, B, C or a U followed by 4 digits. The technician can ascertain the exact nature of the problem from the code.

When should you replace your ECU?

• Repairing an ECU can be tricky.
• It involves a complete disassembly and is an extremely precise and detailed electronic operation, just like repairing a computer or smartphone. 
• They are highly advanced pieces of technology that affects every component of the engine. 
• Replacement of a damaged ECU is a better alternative. 
• A trusted online used engine store will reprogram and ship and undamaged originally retrieved ECU from an undamaged vehicle. 
• The old data from the ECM will be cleared and newly programmed for you. 
• A trusted online store like Big Mouth Direct will match the ECU with your car model and year. You may also get an updated version. 
• You will save thousands of dollars when compared to an OEM Engine Control Unit. 
• Repairing the engine computer can get complicated and you can run into various problems ending up spending more than purchasing a used engine control unit.
  

What to check when buying a used ECU?

• Run a scan via the OBD2 port if you can.
• That could show a recently cleared fault code.
• Ask the dealer what codes were cleared and why. 
• Check the unit for an external chip. 
• Check the number on the label (by all the bar codes) and match yours, the last three digits are important.

Why trust Big Mouth Direct?

• Warranty offered for 30 days. 
• They have a thorough understanding of the part and each part is fully checked before delivery.  
• Trust a company that cares and values a customer’s requirement.
