 More details

Power System

The natural gas from the ramp of attack of the overall network. reaches the carburetor venturi, which also comes clean air after crossing the corresponding dry filter. The gas / air mixture produced in the carburetor, is absorbed by the turbocharger.

 In the carburetor fuel mixture is established based on a high excess air factor. that allows to keep the content of pollutants such as NOx, CO and hydrocarbons from incomplete combustion of gas, below the values allowed by current standards of environmental control.

According to law                                                Motor GS-NL

CO < 500 p.p.m                 420 p.p.m

NOx < 300 p.p.m               210 p.p.m

 The turbocharger, driven by engine exhaust gases, vacuum and compress the fuel mixture, propelling it through a cooler that lowers the volume specific, focused and increasing engine power. Then the fuel mixture, properly conditioned is injected into the cylinders.

 1.3 System Lubrication

The lubrication of the motor is realised mechanically by the circulation of the oil by means of a pump driven by the motor, and the corresponding filter to guarantee the cleaning of the lubricant. To keep oil temperatures below 80/90 _ C. (to ensure an appropriate viscosity), the heat absorbed during the cycle of oil, is transferred to cooling water in the oil cooler.

The crankcase of the engine will also have a vent to remove air / gas that can be incorporated into the oil, avoiding the risk of explosion. It will very well with a pump and drain the crankcase with a device used oil collection tank with a capacity of 3,000 liters to fill the tanks of each motor

The oil will be supplied by tanker in a tank of 3,000 liters, from east and through a system of pumps in parallel, fill storage tanks on each engine, each of 1,000 liters.  

In addition there will be a waste oil tank of 3,000 liters capacity, where used engine oil will be placed after each change.  

in addition each engine has a crankcase pipe degassing to the atmosphere, finished with a cap to prevent ingress of water and atmospheric dust to remove the condensates will put on a drum with a drain valve, the vent will have a filter to prevent entry of dust.  

1.4 Cooling systems  

There are two cooling systems, one for cooling the second stage of the cooling mixture, and one for the cooling of lubricating oil, the first stage of the cooling mixture, the cooling of the shirts and turbo compressor. Cooling is accomplished through closed circuit that uses a glycol water mix these additives are intended to prevent corrosion and freezing of the engine cooling circuits.

1.4.1 Cooling circuit low temperature.  

The circuit responsible for cooling the intake air, the liquid refrigerant cools the fuel mixture cooler, consisting of a heat exchanger water-fuel mixture.  

This circuit is recirculated by an electric pump through a air cooler and a cooling tower where heat is dissipated.  

The outlet temperature of engine coolant is 43 _ C, and after passing through cooling then re-entering the engine at 40 _ C.

These circuits shall keep a redundant system of pumps operating in parallel.

1.4.2 Cooling circuit high temperature.  

The circuit responsible for the second phase of the mixture and shirts is recirculated by an electric pump through three heat exchangers and a air cooler. In these exchangers plate is where he is recovering part of the heat given off by the engine in this circuit.  

The circuit features a three-way valve pneumatically actuated allowing coolant is recirculated without passing through the heat exchanger plate until it reaches its temperature regime.

These circuits carry a redundant system of pumps operating in parallel.
