Turbocharger, Crankcase Ventilation & Electronic Control Panel: Diesel Engine Performance Essentials

Turbocharger
A turbocharger can significantly boost an engine's horsepower without significantly increasing its weight. It compresses the air flowing into the engine, allowing the engine to squeeze more air into a cylinder. More air means more fuel can be added, leading to increased power from each explosion in each cylinder.

Crankcase
The crankcase ventilation system is designed to maintain a balance between the engine crankcase air pressure and atmospheric pressure.
  • Excessive pressure variations can negatively affect component life, the lubrication system, and overall engine emissions.
  • Proper ventilation ensures optimal engine performance and longevity.
Electronic Control Panel (ECP)


The Electronic Control Panel (ECP) plays a crucial role in managing engine speed and fuel flow:
  • A magnetic pickup sensor detects engine speed at the flywheel ring gear, generating an AC voltage proportional to the engine speed.
  • The actuator controls fuel flow from the fuel pump to the injectors.
  • The actuator valve remains normally closed and opens depending on the current through the actuator coil.
  • The ECP compares the signal from the magnetic pickup with a pre-set speed reference point (e.g., 1500 RPM).
  • If there is a discrepancy between the actual and reference speed, the controller adjusts the actuator current to maintain the desired speed.
The turbocharger, crankcase ventilation system, and electronic control panel are essential components that enhance engine efficiency, power output, and performance. Proper understanding and maintenance of these systems ensure optimal engine operation and longevity.

Fire Extinguishers: Types, Operation & Best Uses for Fire Classes

A fire extinguisher is an active fire protection device used to extinguish or control small fires, often in emergency situations. Typically, a fire extinguisher consists of a hand held cylindrical pressure vessel containing an agent which can be discharged to extinguish a fire. There are two operation types of fire extinguishers:  i. Stored pressure  ii. Cartridge operated  Stored Pressure  In stored pressure units, the expellant is stored in the same chamber as the fire fighting agent itself. Depending on the agent used, different propellants are used. With dry chemical extinguishers, nitrogen is typically used; water and foam extinguishers typically use air.  Cartridge Operated  Cartridge-operated extinguishers contain the expellant gas in a separate cartridge that is punctured prior to discharge, exposing the propellant to the extinguishing agent. This type is not as common, used primarily in areas such as industrial ...

Important components of a Diesel Engine - Turbocharger

Important components of a Diesel Engine Turbocharger A turbocharger can significantly increase an engine’s horsepower without adding significant weight. It enhances engine performance by forcing more air into the combustion chamber, enabling better fuel combustion. A turbocharger is made up of two main sections: The turbine and the compressor.  The turbine consists of the turbine wheel and the turbine housing.  It is the job of the turbine housing to guide the exhaust gas into the turbine wheel. The energy from the exhaust gas turns the turbine wheel, and the gas then exits the turbine housing through an exhaust outlet area. The compressor also consists of two parts: the compressor wheel and the compressor housing.  The compressor’s mode of action is opposite that of the turbine. The compressor wheel is attached to the turbine by a forged steel shaft, and as the turbine turns the compressor wheel, the high-velocity spinning draws in air and c...

Sewage Treatment Plant - Filter Feed Pumps Types and Operation And Maintenance Considerations

FILTER FEED PUMPS Filter Feed Pumps are used to draw water from the clarified water sump and pass it through the Pressure Sand Filter (PSF) and Activated Carbon Filter (ACF), which are installed in series to improve water quality. PRESSURE SAND FILTER (PSF) Working Principle: The upper layers of sand perform the actual filtration function, while gravel layers provide physical support. Specialized sand with a specific particle size is used to trap solid impurities present in water. The particles get entrapped in the spaces between sand grains, eventually blocking water flow. When the pressure drops beyond a set limit, the sand is cleaned by backwashing with water. Backwashing reverses the flow, fluidizing the sand bed and removing lighter solid particles as waste. Operation And Maintenance Considerations Filtration is followed by a short backwash sequence. The filter requires backwashing when the pressure drop across the filter reaches 0.5 kg/cm². Best practice: Backwash once per shift,...
