Hallo teman - teman semua, ketemu lagi dengan dhevils mechanic di tulisan - tulisan yang tak jauh dari dunia mechanic Oil nad Gas industry, Dan kali ini kita membahas engine genset yang lumayan mulai berkembang pemasarannya di indonesia dari tahun 2008 hingga sekarang. walau untuk saat ini kita sudah jarah mendengar penambahan unit untuk wilayah indoensia yaitu gas engine generator dengan merk Guascor.
Gas engine di produksi oleh negara spanyol dengan pemasaran saat ini dipengang oleh dresser rand group dan berikut spesifikasi dari gas engine generator dengen merk Guascor model SFGLD 560 yang dirangkum dari berbagi sumber

❚Operating parameters – Otto Cycle, four-stroke, V-16 engine turbocharged with lean burn operation
❚Engine block – alloyed and heat treated cast iron; standard inspection ports for the crankshaft and camshaft
❚Flywheel housing – SAE 00, 18-inch with ring gear
❚Cylinder liners – spun cast grey pig iron; liners cooled by main engine coolant circuit and removable for easy service
❚Cylinder heads – individual cylinder heads grey cast iron; heads are water-cooled with four valves per cylinder and a centered spark plug❚
Crankshaft – press forge hardened and tempered alloy steel; crankshaft dynamically balanced; two vibration dampeners on the Vee engines and one on inline engines
❚Camshaft – alloy steel, induction hardened, gear-driven
❚Connecting rods – forged, hardened, tempered alloy steel
❚Pistons – aluminum alloy with three rings and a specially designed combustion chamber shape for maximum efficiency and minimum emissions; pistons cooled using oil jets directed at the underside of the piston
❚Water-cooled exhaust manifolds
❚Two-stage intercoolingSPECIFICATIONS
❚Starting system – 24V DC starting system; two starters on the Vee engines and one on the inline engines
❚Engine oil pre-lube pump and oil heater
❚Generator, 2/3 pitch, two bearings, temperature rise within 221 degrees F (105 degrees C), and precise voltage and frequency regulation to 0.25%
❚Air / fuel ratio control – gas metering valve provides intelligent control, using engine intake temperature and pressure sensors; provides excellent emissions control and continuous adjustment for varying engine loads and changes in gas supply conditions
❚Electronic ignition – a microprocessor-based digital ignition system optimizes engine combustion and performance, as well as fuel efficiency and spark plug service life; an individual ignition coil is used for each cylinder and a detonation control system is included
❚Cooling system – two independent water cooling circuits for the main engine coolant and the secondary oil and aftercooler circuits; various options available; may include mechanical or electric engine coolant pumps, a shell and tube main circuit heat
