How Inspection of Engine Components is Done After the Engine Dismantle.

by
Inspection of engine components is necessary after the engine is dismantled. The various parts are inspected in this process. In this article, I will discuss the components of the engine that need to be inspected.

Inspection of Engine Components

The inspection procedure is detailed in the following paragraphs and covers the complete overhaul of the engine with that unit taken out of the vehicle. Before commencing the inspection and repair operations, the following inspections should be kept in mind. 
 
> During and immediately after disassembly, inspect the cylinder block and head for evidence of water leakage or damage after washing them clean, inspect more closely.
 
> Wash and clean all the disassembled parts. Remove the grease and the carbon particles. Be sure to the dirt and clean the passages of the water jackets.
 
> Use compressed air to clean internal engine oil holes and passages.
 
> Do not disturb the sets of combinations of valves, bearings, bearing caps, etc.
 
The other important components of the engine are discussed in the article below. 
 

Cylinder Head

The cylinder head needs to be examined in a proper manner. The process is- 
 
> Remove all the carbon from the combustion chamber.
 
> Check the cylinder head for cracks in the intake and exhaust ports, combustion chamber, and head surfaces.
 
> Check the flatness of the gasket surface. For checking the surface location use the perfect tool recommended by the owner guide. If the distortion limit of 0.05 mm is exceeded, correct the gasket surface plate using an abrasive paper of about 400(waterproof silicon carbide abrasive paper). Place the paper over the surface plate and rub the gasket surface to grind off the uneven spots. Should this fall to reduce the thickness gauge readings within the limit, replace the cylinder head.  Leakage of the combustion gases from the gasket joint often occurs due to a wrapped gasket surface. Such leakage results in a reduced power output.

How To Measure the Specific Gravity of a Battery?

A fully charged battery is a helpful and prominent helper for your car. In this article, I will discuss how to Measure the Specific Gravity of a Battery?

Measure the Specific Gravity of a Battery

The specific gravity is the most critical parameter, that needs to be checked and maintained for the good health of the battery. The measuring unit is the density of electrolytes present in the battery compared to the density of water. 
 
When the battery is fully charged the specific gravity will be at a higher point and when the battery is discharged the specific gravity will fall down. To measure the specific gravity of a battery the Hydrometer is used. 
 
A Hydrometer is a simple device that works on the principle of buoyancy. As the density of the electrolyte changes with the state of charge, the hydrometer float will further sink deeper or rise higher. Thus it indicates the specific gravity. First, we need to know what is specific gravity and how the hydrometer measures it?
 
 

What is Specific Gravity?

The electrolyte in a fully charged battery is usually 1.23 times as heavy as an equal volume of pure water when both liquids are at the same temperature. The battery electrolyte would, therefore be described as having a specific gravity of 1.230 meaning that its weight is 1.230 times the weight of pure water. 
 
When the battery discharges the Sulphuric acid in the electrolyte combines with the plates and the remaining electrolyte becomes lighter in weight. By determining the relative weight of the electrolyte we can tell how much acid has combined with the plates and, therefore, estimate how much electrical energy is still left in the battery. However the actual weighting of the electrolyte would be inconvenient, so an instrument called the Hydrometer is used. 

What is Oil Pressure Gauge?

How to Convert Gasoline Engine to Natural Gas?

by

How to convert gasoline engines to natural gas is the basic question asked by a few people. Basically, a gasoline engine is a traditional engine used for a couple of decades. In this article, I will discuss the process of gasoline conversion to natural gas.

How to Convert Gasoline Engine to Natural Gas

Gasoline engine meets all the requirements expect fuel economy, whereas diesel engine has an advantage. The need of the hour is to achieve the drivability, comfort, and fuel economy of diesel engines. 
 
As experts in the field, we understand the benefits and advantages of using natural gas as a fuel source. Natural gas is a cleaner burning fuel compared to gasoline, emitting fewer pollutants such as carbon monoxide and nitrogen oxides. By converting your engine to natural gas, you contribute to reducing air pollution and greenhouse gas emissions.
