Mitsubishi Diesel Generator Sets 520–1800kW

Q: What is the fuel consumption of a Mitsubishi generator?

Mitsubishi generator fuel consumption is 196–221 g/kW·h at 75% load depending on engine family: the S6R2 series uses 196–203 g/kW·h, the S12R series 199–221 g/kW·h, and the S16R/S16R2 series 200–209 g/kW·h. The most efficient engine in the lineup is the S6R2-PTA at 196 g/kW·h, used in the R-JM (imported) series. In litres, Mitsubishi sets consume about 72.9 L/h at 520kW, 170.4 L/h at 1,200kW and 269.0 L/h at 1,800kW at 75% load. Figures are measured per ISO 3046-1 and vary about ±5% with ambient conditions and load profile; the power range table above lists L/h at 75% and 100% for every model.

Q: Which Mitsubishi series is right for my project — R-SM or R-JM?

Choose by origin requirement, lead time and price. Specify R-JM when the tender or the end user requires engines built in Japan; specify R-SM when the project allows Chinese production and cost is the priority — the engines are the same MHI design, built by SME in China with the "-C" suffix. Both series cover 520–1,800kW and are matched with Stamford or Leroy-Somer alternators and Deep Sea controllers. H&C also supplies Cummins, Perkins and MTU, so we can compare platforms for your load profile — send your kW, load profile and country.

Q: Are Mitsubishi generators suitable for hot climates and harsh sites?

Mitsubishi engines are factory-rated to 50°C ambient at ISO conditions, with a documented operating range of -30°C to 50°C — so no performance penalty applies in Middle East, African and tropical installations. The S6R, S12R and S16R designs use mechanical fuel injection, so there is no common-rail electronics to fail in high-temperature, high-humidity or high-dust conditions, and they accept wider variation in fuel quality. Starting performance is 10 seconds to full load with 100% single-step load acceptance. Tell us the site ambient temperature, altitude and fuel quality and we will confirm the derating curve for your configuration.

Q: What is the delivery time for a Mitsubishi generator set?

The lead time for a Mitsubishi generator set depends on which series you choose, the engine model, the quantity and the factory's current schedule. R-SM (China-built) and R-JM (imported) engines come from different production sources, so their lead times differ and are confirmed against the factory's current schedule rather than quoted as a fixed figure. Send the engine model and the quantity you need and we will confirm the current factory lead time for your order.

Why Choose Mitsubishi Diesel Generators?

Mitsubishi Heavy Industries (MHI) engines deliver Japanese precision engineering with a low failure rate — MHI builds its own fuel pump, turbocharger and injectors. The S6R, S12R and S16R engine families are purpose-built for power generation, with an operating range of -30°C to 50°C.

H&C offers both the R-SM (SME) and R-JM (JM) Mitsubishi-powered series — from the S6R2 6-cylinder (520kW) to the S16R2 16-cylinder (1,800kW). JM is built in Japan; SM is built in the China joint venture with a "-C" model suffix — same models and technology. Each genset is paired with a Leroy-Somer or Stamford alternator and Deep Sea 7320 controller, assembled and load-tested at our manufacturing facility in Jiangsu, China.

For sites in the Middle East, Africa, and high-temperature regions, Mitsubishi is engineered for harsh conditions: 10-second start, 100% one-step load acceptance, and 300% momentary overload — specified for data-center designs targeting Uptime Institute Tier III/IV.

Frequently Asked Questions — Mitsubishi Generators

How much does a Mitsubishi diesel generator cost?+

A Mitsubishi generator set is priced by power rating, engine series and configuration. H&C builds Mitsubishi-powered sets from 520kW to 1,800kW in two series: R-SM, using engines built by Shanghai MHI Engine (SME), MHI's engine joint venture in China, and R-JM, utilizzando imported Japan-built engines. Because the two series come from different production sources, their prices differ — R-JM carries Japanese production and import costs, while R-SM is the more economical route for projects that do not specify a Japanese origin. Alternator choice (Stamford S5–S7 or Leroy-Somer TAL/LSA), enclosure (open skid, tenda insonorizzata or containerized) and controller options (Deep Sea DSE 8610 or DSE 7320 standard; ComAp and SmartGen optional) also affect the final price. Tell us the required kW, voltage and destination country, and we will confirm the R-SM or R-JM price within 24 ore.

What is the fuel consumption of a Mitsubishi generator?+

Mitsubishi generator fuel consumption is 196–221 g/kW·h at 75% load depending on engine family: the S6R2 series uses 196–203 g/kW·h, the S12R series 199–221 g/kW·h, and the S16R/S16R2 series 200–209 g/kW·h. The most efficient engine in the lineup is the S6R2-PTA at 196 g/kW·h, used in the R-JM (imported) series. In litres, Mitsubishi sets consume about 72.9 l/h a 520 kW, 170.4 l/h a 1,200 kW and 269.0 l/h a 1,800 kW at 75% load. Figures are measured per ISO 3046-1 and vary about ±5% with ambient conditions and load profile; the tabella della gamma di potenza sopra sono riportati i valori L/h al 75% e al 100% per ogni modello.

Where are Mitsubishi generator engines manufactured?+

Mitsubishi generator engines reach H&C from two production sources. The R-JM series uses importati Mitsubishi engines built in Japan — the model code has no suffix (for example S6R2-PTA). The R-SM series uses engines built by Shanghai MHI Engine (SME), Mitsubishi Heavy Industries' engine joint venture in China — the model code carries the "-C" suffix (for example S6R2-PTA-C). Both are MHI-licensed designs on the same S6R, S12R and S16R architecture, with parts interchangeability above 85%, and both cover Da 520 kW a 1,800 kW. Tell us whether your project specifies a Japanese or a Chinese production origin and we will quote the matching series.

Which Mitsubishi series is right for my project — R-SM or R-JM?+

Scegli per origin requirement, lead time and price. Specificare R-JM when the tender or the end user requires engines built in Japan; specify R-SM when the project allows Chinese production and cost is the priority — the engines are the same MHI design, built by SME in China with the "-C" suffix. Both series cover 520–1,800kW and are matched with Stamford or Leroy-Somer alternators and Deep Sea controllers. H&C also supplies Cummins, Perkins and MTU, so we can compare platforms for your load profile — send your kW, load profile and country.

Are Mitsubishi generators suitable for hot climates and harsh sites?+

Mitsubishi engines are factory-rated to Ambiente 50°C at ISO conditions, with a documented operating range of -30 ° C a 50 ° C — so no performance penalty applies in Middle East, African and tropical installations. The S6R, S12R and S16R designs use iniezione meccanica del carburante, so there is no common-rail electronics to fail in high-temperature, high-humidity or high-dust conditions, and they accept wider variation in fuel quality. Starting performance is 10 seconds to full load with 100% single-step load acceptance. Tell us the site ambient temperature, altitude and fuel quality and we will confirm the derating curve for your configuration.

What is the delivery time for a Mitsubishi generator set?+

The lead time for a Mitsubishi generator set depends on which series you choose, il modello del motore, il quantità e factory's current schedule. R-SM (China-built) and R-JM (imported) engines come from different production sources, so their lead times differ and are confirmed against the factory's current schedule rather than quoted as a fixed figure. Send the engine model and the quantity you need and we will confirm the current factory lead time for your order.
