The major maintenance required by Guascor gas engines is also known as maintenance type R3.

Commonly, this type of preventive maintenance is carried our each 50.400 running hours (whatever the gas the engine consumes).

In this occasion, we show you some pictures of genuine spare parts we used to carry out the engine Overhaul of that Guascor engine in our facilities.

Required labor in our facilities was 1-2 weeks in this case, in order to finish everything. Main repairs, renews, and refurbishments we carried out were the following ones:

  • Renew of main bearings.
  • Renew oil pump and water pump.
  • Renew all pistons, cylinder liners.
  • Refurbishment of con-rods, changing the small end bushings and the bolts.
  • Refurbishment of all cylinder heads.
  • Check status of engine block, crankshaft and camshaft.
  • Renew turbocharger.
  • Generator/alternator standard checking.
  • Renew intercooler.
  • Renew spark plugs, ignition coils and ignition cables.
  • Renew oil filters and air filters.
  • Renew main vibration damper.
  • Renew starter.
  • Renew thermostats.
  • Painting.

Definitely these are the labors needed on a maintenance type R3 of any Guascor engine. Anyway, we could carry out it “on-site” if the customer does not want to ship the engine out of its Power Plant, or in case the execution time is too short.

In short, we hope you trust in «RS Motor» to supply spare parts for your Guascor engine, as well as for refurbishing their parts, or even to carry out all needed preventive and/or corrective maintenances. Many customers already believe in us!.

You can be the next one, try!!!

This time we show you how we usually perform a maintenance type 40.000 running hours on Jenbacher type 6 gas engines, which runs with Natural Gas.

For this type of preventive maintenance, our team goes to the customer’s Power Plant. Anyway, there are some labors which «RS Motor» has to perform in the workshop. These labors are highlighted with the symbol “*”.

40.000 HOURS MAINTENANCE CHECKLIST ON JENBACHER J620 GAS ENGINE

» Disassembly of the intercooler for subsequent delivery to «RS Motor». The intercooler will undergo ultrasound cleaning, which consists of the following steps (*):

  1. Preliminary visual inspection and exterior appearance check.
  2. Preliminary hydraulic test to verify absence of leaks.
  3. Dismantling of all covers.
  4. Replacement of fixing elements.
  5. Repair of female threads of the intercooler tube bundle.
  6. Cleaning of tube bundle and covers by using an ultrasonic cleaning machine.
  7. Renew of water side gaskets.
  8. Inner and outlet painting of water side covers.
  9. Complete assembly of the intercooler, respecting the recommended tightening according to the standard requirements.
  10. Final hydraulic test for 8-12 hours for product validation, prior to its assembly and installation on the engine.

» Replacement of precombustion chambers with their respective O-rings. Removal of cylinder heads on the engine is excluded.

» Replacement of the rocker cover gaskets.

» Intake and exhaust valve timing.

» Degreasing of the gas injection valves.

» Replacement of the rubber springs which have not able for being installed again.

» Renew the actuator linkage.

» Replacement of the main lubricating oil filter.

» Renew throttle valves.

» Replacement of air filters.

» Renew 2x vibration dampers.

» Replacement of the elastic coupling generator-engine.

» Renew crankcase ventilation filters.

» Checking of high connections and wiring.

» Disassembly of the exhaust gas turbocharger and subsequent mounting on the engine. Turbocharger standard maintenance or cleaning can be considered or not, depending on the customer’s decision.

» Cleaning the battery connection terminals.

» Standard refurbishment of the 2x starters with replacement of shaft, bearings, relay and seal (*). Optional.

» Overhaul of the main lubricating oil pump with bushings replacement (*). Optional.

» Replacement of gaskets, screws and other minor spare parts.

» Complete engine assembly.

» Engine connection, commissioning and subsequent checking of control parameters through DIA.NE control system.

 

These are the main steps that «RS Motor» takes into account to perform a 40.000 hours maintenance on Jenbacher type 6 gas engines.

Do not hesitate to ask us for price and availability wherever your engine or power plant is. We are available worldwide. Our field engineers and technicians will do their best with your engine.

Catalysts

Along this article, we want to talk about one of the main enviromental challenges that CHP plants are facing nowadays.

The reduction of pollutants to the atmosphere, is a key aspect within the use of Natural Gas or Biogas Reciprocating Engines to produce Heat and Power.

Thoughout the last years the legislation in terms of Hazard emissions to the atmosphere all over the world has become more restrictive with lower limit values, therefore sometimes is compulsory find Solutions to cut down the different values under the legal limits.

In many cases, the solution that allows be inside the legal emission values is using a catalyst element.

The most common catalyst, are the next:

SELECTIVE CATALYTIC REDUCTION – SCR 

Nitrogen Oxides are commonly the main headache about the atmospheric contamination when we talk about the emissions control of gas engines.

SCR catalyst (selective catalytic reduction), are used to cut down the NOx levels in the exhaust gases. The exhaust gases are mixed with a metered amount of Ad-Blue, afterwards the pollutant gases go throuhgh a Surface of a ceramic honeycomb, coated with noble metals where the NOx are reduced by hydrolysis.

The hydrolysis breaks down the urea, that reacts with the Nitrogen Oxides, turning them into Nitrogen and H2O. To control the levels of NOx a sensor is assembled, thanks to this sensor the Ad-Blue metering is calculated.

The correct Ad-Blue (urea) metering beside their distribution over the catalyst is the key to achive correct pollutant levels.

OXIDATION CATALYST

This kind of catalyst are used to reduce the values of Carbon Monoxide (CO) and un-burnt hydrocarbons, specially formaldehyde.

In the oxidation catalysts, the exhaust gases go through a oxidation element honeycomb, coated with noble metals where the catalytic oxidation is developed to create Hydrogen and Carbon Dioxide, cutting down the Hazard elements in the exhaust gases.

CONCLUSION

With the aim of ensure the engines are running within the legal pollutant limits, producing heat and power on a efficient way, «RS MOTOR» has the ability to carry out catalyst projects for the correct exhaust gas treatmet.

Below you will see some images from a recent instalation of a Oxidation Catalyst carried out by «RS MOTOR».
