Hva er ulovlig av motorer?

Det er ikke 2-taktere som er forbudt, det er nye 2-takts forgassermotorer, som er forbudt og importere, med mindre de klarer de nye utslippskravene.

 

Dette gjelder foreløpig bare i norge tror jeg.

 

Forhandlerene importerte jo en del før nyttår, så det er fortsatt fult mulig og kjøpe nye 2-takts forgassermotorer

Okey, har dere hørt om CARB 2008 + medfølgende opptil 3 stjerner og EPA 2006?

Tror dere tar litt feil her jeg da. Vanlig 2-taktere med forgasser ja, men ikke 2-takt DFI motorer.

EXHAUST & NOISE EMISSIONS STANDARDS ETC..   

     

Emissions Regulations: The Truth    There has been, and still is a lot of serious misinformation concerning the EU 2006 emission regulations. Firstly, these are the ONLY regulations that affect recreational outboards sold in the UK and the rest of the EU. Regarding NEW outboard motors, only new technology (Direct Injection) spark ignition two stroke (for example, the Evinrude E-TEC range), spark ignition four stroke and compression ignition engines meet the new standards and are the only outboards which may be manufactured within, or imported into the EU now. Spark ignition means all engines powered by petrol / gas, whilst compression ignition means engines powered by diesel. HOWEVER, contrary to popular belief, ALL outboard motors in use prior to the implementation of the new standard CAN continue to be used until they fall apart! The new directive does NOT BAN USE of conventional 2-STROKES. Not only that, but ALL UNSOLD non-compliant 2-stroke outboards which were already in the EU before 1st January 2007 (for non-compliant four strokes, the date was one year before) may still be BOUGHT, SOLD AND USED. Second-hand outboards will still be able to be sold in the normal manner. It has always been possible that an authority in charge of a particular area may impose their own local regulations. This applies primarily on inland waterways, and is most common on reservoirs, which often ban all engines except electric. So to reiterate, EVERY outboard motor in the EU prior to the implementation of the new standard CAN be bought, sold and used under the EU 2006 emissions directive. e.&.o.e. ©   

EU 2006 Standard    EU 2006 Emissions Standards Label represents conformity to the EU emissions standards proposed by the Commission of the European Communities on 12th October 2000. IT IS THE ONLY EMISSION STANDARD THAT AFFECTS UK AND EU ENGINES. All other emission standards are irrelevant for the UK and the rest of the EU (for example EPA 2006, CARB 2004 /2008). The EU2006 standards will only affect the SUPPLY of NEW outboards for ‘RECREATIONAL’ use. By ‘recreational’, the regulators exclude engines for commercial registered vessels and racing engines. This text only is only with regard to recreational engines. ALL engines sold PRIOR to the full implementation of the standards on the dates shown below, may continue to be used. Effectively, after 31st December 2006, any NEW spark ignition two stroke outboard motor which does not meet the EU 2006 standards, (basically conventional carburettor / E.F.I. 2-strokes) will cease to be imported / manufactured into the EU. However, any engines held in stock by EU importers or dealers, which have been tax paid, are exempt, in the same way as though they had been sold prior to the regulations. Equally, only spark ignition four stroke and compression ignition (diesel) outboards, which meet the regulations, may be sold from 31st December 2005, with the same exemption about stock units. It should be noted that the spark ignition four stroke and compression ignition engines are required to meet the regulations a year earlier than spark ignition 2-strokes. (For more details see "Emissions: The Truth") Unlike the EPA and CARB standards, the EU 2006 standard covers three constituents of exhaust emissions, and noise levels. The exhaust emissions included are nitrous oxide and hydrocarbons (as included in EPA & CARB standards) plus carbon monoxide. Consequently the EU 2006 standard is the most difficult to attain compared with EPA and CARB. Unlike the US standards that allow a percentage of ‘dirty’ engines to be sold, the EU 2006 standard will affect EVERY NEW engine sold in the EU. The EU 2006 standard is also the only standard that also covers noise levels for outboards. It should be noted that the EU2006 standard also affects inboard engines in a similar manner to outboards. e.&.o.e. ©   

CARB 2004 / 2008 (U.S.)    EPA 2006 Standards label shows compliance with the U.S. Environmental Protection Agency exhaust emission standards. It covers nitrous oxide and hydrocarbon emissions. Conventional 2-strokes are unable to meet these standards. EPA standards are an indication of low emissions, but have no official status in the UK. e.&o.e. ©   

EPA 2006 (U.S.)    CARB standards are an indication of low emissions, but have no official status in the UK or the EU. CARB 2004 Two Star label (Very Low Emissions) and CARB 2008 Three Star label (Ultra Low Emissions) represents compliance with the California Air Resources Board standards, which will be implemented in 2004 and 2008 respectively. These standards are very strict, with the two star CARB 2004 standards representing 20% lower emissions than the EPA 2006 standards whilst the ultra strict CARB 2008 standards, represented by the three star label, represents a phenomenal 65% reduction of nitrous oxide (NO) and hydrocarbon emissions compared to the EPA 2006 standards. Presently, the three star CARB 2008 standards have the lowest limits FOR THE GASES THEY REPRESENT, compared with EPA 2006 and EU 2006 standards. Please note that the EU 2006 standard also includes carbon monoxide (CO) and noise emissions. As the CARB standards do not measure CO, they are able to have a lower nitrous oxide limit as there is a direct relation between Nitrous oxide and carbon monoxide. If the output of one is lowered, the quantity of the other is raised. In the USA the regulators are not concerned with carbon monoxide (even though it is a lethal, odourless and colourless gas!) and thus have set the nitrous oxide limit extremely low. The effect of this is that although the engines may be adjusted to meet this limit, the carbon monoxide output level has increased dramatically. Consequently, the EU 2006 European standard is actually much more difficult to meet than the CARB standards. Compared to old 1998 limits, CARB 2008 limits are 90% lower! e.&.o.e. ©

Hadde litt bedre info fra ett annet sted, men hukser ikke hvor så har ikke link.

 

Dere kan også se her, hvilke mercury motorer som er godkjent av/etter California Air Resources Board sine krav. (klikk på ultra lov merke til høyre på siden)

Hmm. Høres interessant ut.

 

Grunnen til at jeg lurte var at en kamerat av meg skulle kjøpe ny 30 hk to takter hos Yamaha, men så sa forhandleren at de hadde slutte å selge to-taktere pga for mye Nox utslipp.

 

Men hva er forskjellen på to-takter med forgasser og uten da? (Er ikke ekspert på motordeler og slikt).  :)

Det kan nok stemme ja, for yamaha har kun 4-takt. Altså ikke 2-takt innsprøytningsmotorer.

 

Ta for eksempel min mercury 115 optimax 2007mod, (forøverig holder den carb 2008 tre-stjerner) den er lik 4-takt motorer på alle måter bortsett fra at veiv osv ikke bader i olje. Spesiell 2takt olje bli tilført via egne slanger/kanaler til smørepunkt rundt om i motoren. Nye DFI motorer forbrenner ikke olje lenger slik som gammel 2-taktere med forgasser/forgassere med elektriske dyser.

 

Ref her, siste linje i det tidligere innlegget mitt.

Compared to old 1998 limits, CARB 2008 limits are 90% lower!

Rimelig knallhard forbedring i 2-takt teknologi

Noe olje forbrenner den vel, i og med at den faktisk bruker olje?

er kamaksel på den forresten?

Lenke til kommentar

ja det er sant, den/de (dfi) brenner noe olje. Hvertfall optimax opererer på mye høyere temperatur også. Den er noe spesiell dfi oljen i sammensettingen i forhold til vanlig tcw3 olje. Men nå har jeg ikke helt satt meg inn i oppbyggingen spes da min optimax, men er vel kamaksel ja. (mener jeg å huske)

 

*Fant en publikasjon, dette er 2 motorer fra Mercury på samme båt.
