| − | The | + | The 1.8 Litre 4G93 with it's longer 89mm stroke with the same 81mm bore as the 4G92 giving a displacement of 1834cc is the most varied of the engine family. |
| − | + | It first appeared in 1991 in the Japanese market RVR wagon with SOHC, fuel injection and a 9.5:1 compression ratio. It produced 88kW at 6000 rpm and 159 Nm at 4500 rpm, with the same engine later used in the Japanese Libero and the Australian CC-CE Lancer and Pajero iO. | |
| + | |||
| + | Mitsubishi also released a high-performance version of the 4G93 using DOHC and a TD04 turbocharger with air-to-air intercooler with a 8.5:1 compression ratio to produce 143kW at 6000 rpm and 270 Nm at 3000 rpm. It required premium unleaded fuel and was released in the late 1991 Japanese market Lancer GSR and RS. It came to Australia in the CC Lancer GSR where it was detuned to run on standard unleaded and output 141kW at 6000rpm and 255Nm Nm at 3000rpm. Power was increased to 145 kW in the Australian Lancer from 1995. | ||

| + | A higher output version of the 4G93 Turbo was introduced in 1994 to the Japanese market Libero GT and Lancer GSR/RS and Mirage VR-X AWD where it was given a higher 9.0:1 compression ratio to produce 151 kW at 6000 rpm and 275 Nm at 3000 rpm. Later incarnations of the Libero GT were upgraded to 158kW and 284 Nm. | ||
| + | |||
| + | A SOHC electonic carburetted 4G93 appeared in the base-model Emeraude, Eterna and Galant producing 81 kW at 6000 rpm and 154 Nm at 3000rpm. | ||
| + | |||
| + | Mitsubishi produced a non-turbo fuel injected DOHC 4G93 in it's Japanese Libero Vienta II, Eterna Visage S and Galant with a 9.5:1 compression ratio producing 103kW at 65000 rpm and 167 Nm at 5000 rpm. | ||
| + | |||
| + | In August 1996, Mitsubishi broke new ground when it released the first modern Gasoline Direct Injection engine with the 4G93. | ||
| + | |||
| + | It was initially released in the Japanese Legnum and mid-spec Galant with DOHC and an increased 12.0:1 compression ratio. Requiring premium unleaded, the engine output 110 kW at 6500 rpm and 178 Nm at 5000 rpm. Fuel consumption is reputed to be as low as 5.3 litres/100 Km [http://www.cars-directory.net/specs/mitsubishi/galant/1996_8/16133/] thanks to the ultra lean air-fuel ratios made possible by the GDI system. In 1997, the 4G93 GDI appeared in Europe under the bonnet of the Carisma and Volvo S40/V40. From 1997 onwards, power and torque slid to 103 kW at 6000 rpm and 181 Nm at 3750 rpm in all 4G93 DOHC GDI engines. | ||
| + | |||
| + | In 1998, the Japanese Pajero iO was the next model to come with the 4G93 GDI with power again slipping, this time to 96 kW at 5500 rpm and 181 Nm at 3500 rpm (the same specfications later appeared in the 2000 Lancer Cedia) 1998 also saw the introduction of 'quiet/low exhaust' specification Galant and Legnums which reduced power to 99 kW at 6000 rpm and 177 Nm at 3750 rpm. Power in standard spec vehicles remained the same. | ||
| + | |||
| + | In 2000, Mitsubishi released its first GDI Turbo in the Pajero iO TR. Using a high (for turbo) 10.0:1 compression ratio the engine also used an air-to-air intercooler to produce 118 kW at 5200 rpm and 220 Nm at 3500 rpm. The engine later appeared (mounted east-west) in the Lancer Cedia wagon and Dion van to produce a healthier 121 kW at 5500 rpm and 220 Nm at 3500 rpm. | ||
