What types of Landi Renzo gas equipment are there?

The company produces the following automotive gas equipment systems:

EVO: the main components are - an electronic control unit (ECU), a gearbox LI - 02 (up to 110 kW), AEB injectors, an indicator button, a PT Gas Map sensor, coarse and fine filters;
Omegas: ECU, Li-10 gearbox (for naturally aspirated and turbocharged TwinAir and MultiAir engines), Girs injectors;
Direct: ECU, Li-10 gearbox, MED injectors.

The main differences between them are in electronic control units, gearboxes and injectors. The remaining components are identical in design and function.

ECU Landirenzo Omegas Direct 3-4/ Landirenzo Omegas Direct 5-8

This is the latest innovation from Landi Renzo - fourth generation premium equipment. Designed for injection engines with direct fuel injection (TSI, FSI, TFSI) when converted to propane - butane (liquefied gas) and methane (natural gas).

It is used in the world's most famous automobile brands - Mersedes, Toyota, BMW and others. For each of them, individual ECU firmware is performed, which eliminates any malfunctions in the system.

Electronic control unit Landi Renzo Omegas

Provides constant cleaning of gasoline injectors when the engine is running on gas. Minimum portions of gasoline supplied to the injectors at the command of the ECU prevent overheating, coking and burnout.

This electronic control unit has wide applications. It is suitable for any four-cylinder engine (Landirenzo Omegas Direct 3-4). Also used for five to eight cylinders (Landirenzo Omegas Direct 5-8).

The unit is adapted to OBD II. Provides ignition timing using its own software and hardware.

The entire gas equipment system is delivered from the factory as ready for use as possible. This eliminates the need to define many necessary parameters and simplifies the setup process. As a rule, a simple auto calibration is sufficient, and the car is ready to use gas as a motor fuel.

Landi Renzo gearboxes

Can be used for both naturally aspirated and turbocharged (TwinAir, MultiAir) engines. Available modifications:

Gas reducer IG 1Magg

LI - 10 (up to 140 kW);
10 Turbo (up to 160 kW);
LI - 10 Magg (more than 160 kW). Brand IG 1 is the most powerful gearbox (from 192 to 246 hp), has a two-stage gas pressure reduction design. Weight - 1.87 kg.

To increase safety, all modifications of gearboxes are equipped with solenoid valves. To purify the gas, there is a fuel (gas) coarse filter at the inlet.

Design features of gearboxes

These include:

devices do not have plastic parts, which increases their reliability;
increased heat transfer area due to the ribbing of the heat exchanger. Thanks to this, the gearbox heats up very quickly;
single-stage, except for the Landi Renzo IG 1 magg brand, which has two stages of pressure reduction and, accordingly, two diaphragms interconnected during operation. This ensures high sensitivity of the gearbox, which has a positive effect on the dynamic characteristics of the car when driving on gas;
the relative position of the cavity for the fluid heating the gearbox (antifreeze) and the membrane is such that in the event of a possible rupture, the gas will not enter the engine cooling system;
an emergency release valve is provided overpressure gas if necessary (when the pressure reaches more than 2.5 bar)
have three mounting points, which ensures rigidity of installation and the ability to mount on a car of any brand.

Landi Renzo gearbox

The condensate is drained through an easily accessible drain fitting provided in a special tank.

Performance and adjustments

Gearboxes provide:

required gas pressure under any engine operating modes;
quickly respond to changes in engine operation;
the engine runs without failures;
dynamic car acceleration;
minimum gas consumption;
productivity - up to 40 kg of gas per hour;
operating temperature - from -20°С to +120°С.

Basic gearbox adjustments are made at the factory. An additional manual speed control is provided idle speed, which runs independently.

Injectors

MED injectors have high accuracy dosage and opening and closing speed. Can be used for both propane-butane mixture and methane. Installation of a gas pressure and temperature sensor on the nozzle rail is provided.

Six types of nozzles are available, differing in color design. Let's look at each of them.

Landi Renzo Medium Blue

These blue nozzles have a disc design, which ensures high speed their triggering. Equipped with caps blue(similar to black, but with improved design). This indicates their power: 15 - 30 kW or 20 - 40 hp per cylinder.

For a four-cylinder engine, one injector rail is required. Here the power with such injectors will be 60 - 120 kW or 80 - 160 hp. For an eight-cylinder power unit, two of them are needed, and accordingly the power will then double.

The ramp body is made of plastic and equipped with a special connector for connecting pressure and vacuum sensors. Connection dimensions: input - 14 mm, output - 5 mm.

Landi Renzo Small Green

These injectors are green and are used for injection engines with indirect injection. Can be used for both liquefied gas (propane - butane) and compressed gas (methane). Have green caps (analogue - orange).

Power per cylinder is 20 kW (27 hp). Accordingly, the four-injector ramp will have an output of 80 kW (108 hp) for the four-cylinder engine. It is possible to connect a pressure sensor. Otherwise, these injectors have the same characteristics as the “Medium Blue”.

Sensitive to gas quality. Therefore, it is imperative to install a fine fuel filter and monitor its condition.

Landi Renzo Medium Black

These injectors are black and have a power per cylinder of 15 - 30 kW (20 - 49 hp). Analogue - coils with purple caps. Used when converting a car to propane (liquefied gas) or methane (compressed natural gas).

The injectors are collapsible; if repairs are necessary, this feature can be used. It is possible to replace a failed injector, rather than the entire ramp.

Sensitive to the purity of the gas used. Its intensive cleaning is mandatory. To do this, it is possible to install two filters in series, one of which has a sump. Other characteristics are the same as the previously discussed types.

Landi Renzo Large White

White color, used for propane-butane mixture (LPG). Can also be used for natural compressed gas (methane - CNG). Power per cylinder - 24 - 40 kW (34 - 55 hp). Accordingly, the power of the ramp of four injectors for a 4-cylinder engine is 96 - 160 kW (136 - 220 hp).

Landi Renzo Orange

Orange, injector power up to 20 kW per cylinder (27 hp). Ramp power is 80 kW (108 hp) for a four-cylinder engine.

Orange is an analogue of the previously produced green injectors, but more advanced and durable. Repairable, it is possible to replace one injector, and not all on the ramp at the same time. The gas quality requirements and design features are identical to the previous ones.

Landi Renzo Large Purple

Purple, the most powerful injectors from the Landi Renzo manufacturer. Analogue white. The power per cylinder is 25 - 40 kW (34 - 55 hp). The power of one ramp of four injectors is from 100 to 160 kW (from 137 to 220 hp). Two ramps for the eight-cylinder engine - from 200 to 320 kW (274 to 440 hp).

The design of the metal-plastic ramp body provides a connector for connecting a gas pressure and vacuum sensor. The remaining parameters, characteristics and requirements for these nozzles are the same as for those discussed above.

When replacing injectors, it is mandatory that they all be the same color, even if an analogue is used.

Preparation of a dish in any public food service is carried out by heat treatment of food products, therefore a huge range of heating equipment is provided for food outlets. Each dish requires its own method of preparation, but most require the presence technological equipment with different functionality and different thermal methods of processing the product.

It is necessary to clarify that for a professional kitchen there are several types of heating lines. The modern food industry gives preference to combi ovens; such a unit can replace a whole range of equipment. You do not need to buy an oven and a baking oven separately; in a combi oven you can fry and bake many products, from meat to baked goods. A functional and practical device that allows the use of steam treatment and hot air convection with the ability to combine both of these tasks.

Small food preparation organizations and cafes often use convection ovens, which do an excellent job of baking confectionery products with little consumption. electrical energy. Distinctive feature convection oven - compact and lightweight performance at low energy costs. A proofing cabinet is provided for the convection system; it allows you to install the oven for proofing.

Industrial technology has gained particular popularity in the professional kitchen. electric stove, the variety of which has a different number of burners, the presence or absence of an oven, as well as external and internal execution from high-quality stainless steel, increasing the performance properties of the slab. In some cases, if this is not allowed technical specifications kitchens, the company installs industrial gas stoves.

An electric frying pan can be used to prepare fried or stewed dishes from meat, fish or vegetables. This frying pan is equipped with the ability to tip over; if it is not possible to purchase a cast iron one, purchase a frying pan with a stainless steel bowl. To prepare food, different frying surfaces are used, they can be either smooth surface, and with corrugated. Usually frying surface also made of stainless steel high quality or made of cast iron.

To stew food and boil water, use a digester boiler, which can, if necessary, be built directly into the kitchen’s heating system, or use a regular boiler with a tiltable container.

Bakeries and specialized catering establishments where bakery products have to be baked in especially large quantities use baking ovens. Wide range ovens on the market may include working chambers of different sizes and numbers.

Don’t forget about food warmers, which are also widely used in professional kitchens of public catering establishments. This is an electric unit that allows you to store ready-made dishes in a constantly hot state; this is how first and second courses, sauces and side dishes are stored in it. There are model options with different chamber volumes, which are mounted in a table or installed directly on the floor.

A large number of public food outlets use electric boilers to boil water, which also make it possible to prepare hot drinks to suit the visitor’s taste, such as coffee or tea.
