Twee cylinder turbo

[Fre]

Denk aan het potentieel twee van deze motortjes aan elkaar gekoppeld . Een 4 cilinder met 220 pk. Zou wel onder de kap van een GP passen

Doe maar lekker die 1.8 4-cylinder van 130 tot 220 pk. (Klinkt verdacht veel als die aangekondigde 1.8 T-Jet... )

Vond op Italiaspeed deze 2 artikelen over nieuwe motoren & technieken vanaf 2009. Artikelen zijn in het engels, kon nog geen berichten op Nederlandse sites vinden.

A new two-cylinder, 900cc petrol engine will arrive in 2010. This brand-new powerplant, dubbed SGE (Small Gasoline Engine), is expected to be the first of a new modular family built around the individual 450cc cylinder unit.
Head of Fiat Powertrain Technologies, Alfredo Altavilla, has set forth details of his company’s plans for 2009, which reveal a hectic schedule and the debut of a raft of new developments. In an interview with Italian newspaper Corriere della Sera, Altavilla revealed that next year will be an exceptionally busy one for FPT, which will launch onto the market a dual-clutch transmission, its new ‘Multiair’ hydraulic valve actuation technology, and a new type of diesel injector, dubbed ‘Multijet 2’. A newly-developed two-cylinder, 900cc petrol engine will follow in 2010.
This brand-new powerplant, dubbed SGE (Small Gasoline Engine), is expected to be the first of a new modular family built around the individual 450cc cylinder unit. To be offered in three forms – naturally-aspirated, turbocharged, and a flex-fuel ‘Natural Power’ version designed to run on compressed natural gas (CNG) – it is set to replace the naturally-aspirated variants of the long-serving FIRE family, which is currently manufactured in 1.1, 1.2 and 1.4 litre capacities. The new SGE 900cc bi-cylinder engine will initially be offered with a range of four power outputs – 65, 80, 90, and 105bhp. Later, Fiat will also offer the option of a CNG and hydrogen compressed gas solution, similar to that seen in the Panda Aria concept car. Altavilla said that other manufacturers have enquired about the engine’s availability, but did not provide specific details.
Set to finally hit the marketplace next year, Multiair hydraulic valve actuation technology has been under continuous development by Fiat for many years. The Italian carmaker is alone in pursuing this technology, which offers the potential for continual valve adjustment and thus optimised efficiency. Altavilla has previously said that engines equipped with Multiair offer up to 20 per cent more torque, at lower revs, as opposed to a conventional mechanical system.
He also confirmed that the new Multiair technology's debut would be seen on the replacement for the Alfa Romeo 147, Progetto 940, which will make its world premiere at the Frankfurt IAA. The system will debut on the group’s 1.4 FIRE T-Jet engine, before spreading to all Fiat Group petrol engines. These include the SGE, on which it will help to reduce CO2 emissions to below 100g/km.
The new two-cylinder is specifically designed to minimise its environmental impact. Designed for A- and B-segment cars, it will find its way into the 500, Topolino, Grande Punto, next-generation Panda and new Lancia Ypsilon, as well as the low-cost cars being developed by Fiat Brazil. In addition, it features a space-saving integrated inlet manifold, in anticipation of a future hybrid version.
Moreover, Fiat Powertrain is also working on widening its applications of stop-start technology. According to Altavilla in the interview, the technology reduces emissions by an average of 3 to 4 per cent, with a reduction in fuel consumption of up to 15 per cent in city driving.
Meanwhile, on the diesel side of the equation, FPT has been busily developing the next leap ahead in oil-burning technology, Multijet 2, in conjunction with Bosch. Altavilla says that Multijet 2 will mark a great leap forward, equivalent in scope to that of the original introduction of common-rail on the Alfa 156 JTD in 1997. Unlike on that occasion, however, he says that Fiat intends to hang on to the patent for this latest-generation technology. He notes that it offers particular benefits in emissions and, especially, low-rev torque. Like Multiair with petrol engines, Multijet 2 will find its way onto every diesel built by FPT. Saying that it will arrive in the last third of the year, Altavilla suggests that 90 per cent of all diesels will use the technology within a decade.

Bosch start/stop technology can be found in more and more passenger cars and from March 2009, Fiat will present its first model to feature a start/stop system: the Fiat 500. Bosch supplies the specially adapted starter, the engine management system, and the battery sensor. Bosch has been manufacturing this start/stop technology since 2007, and has already delivered more than 500,000 starters, for example, to BMW and Mini.
Stefan Asenkerschbaumer, president of the Bosch Starter Motors and Generators division, believes this market will grow rapidly in the next few years: "In 2008, roughly five percent of all new vehicles in Europe are equipped with a start/stop system. By 2012, we estimate this will be every second newly registered vehicle – most of them with Bosch technology." In the next few months, series production of other cars featuring this Bosch technology is to start – the Kia cee'd, for example.
Test drives by Bosch engineers show that start/stop systems reduce fuel consumption, and thus also CO2 emissions, in the New European Driving Cycle (NEDC) by up to five percent. In the urban component of the NEDC, the saving can be as high as eight percent. Start/stop systems automatically stop the engine when the vehicle is stationary, for example at traffic lights. The engine is restarted as soon as the driver depresses the clutch pedal to put the vehicle back into gear. As starter-based systems are largely based on existing components, their cost-benefit ratio is excellent. And unlike other technologies, this approach is also suitable for cold starts in diesel engines.
In the Fiat 500, the system will initially be available in combination with the Dualogic automated manual transmission and a 1.2-liter engine. Fiat plans to install the system in other variants and models as early as 2009. Bosch has adjusted the service life of the starter to the far greater number of starts. Its powerful electric starter motor as well as low-noise, enhanced meshing mechanics guarantee safe, fast, and quiet engine starts in all situations. Bosch also supplies the engine control unit for the Fiat 500, including the software used to analyze all the relevant sensor data and to stop and start the engine. In addition, the battery sensor is also supplied by Bosch. It computes the current state of battery charge and relays this information to the energy management system.
Bosch start/stop systems can draw on the expertise of the company's starter technology, drivetrain, and energy management fields. Next to the starter, the control software, and a battery sensor, the system as a whole includes a crankshaft sensor and the respective sensors at the pedals. A high efficiency alternator in combination with a deep-cycle resistant battery means that the amount of time the vehicle can remain stationary with the engine switched off is increased.

Dus de moraal van het verhaal: steeds kleiner en krachtiger Is het straks misschien nog eens een keer LEUK om te moeten tanken -]

Is het straks misschien nog eens een keer LEUK om te moeten tanken -]

Maakt mij niet uit....tank toch altijd maar voor €35,-




geintje.....De kleine krachtige motoren komen steeds meer naar voren nu. Zie het al voor me straks. Een dikke LAMBO met een 1.2 sterke motor met een tig turbo's. Als het maar snel gaat..... ~]

[ElSjiepo]

Zijn wel leuke blokjes voor op de brommert....

[Hellfire]

Leuk, zo'n start-stopsysteem. Dan mag ik wel hopen dat die motoren sneller aanslaan dan die van mij. :roll:

Verder erg fijn om te weten dat er iets van een datum aan de 0.9 motoren hangt: nog ongeveer anderhalf jaar wachten.
